After a few years, he decided to become a concrete pumper. So making a long form with plywood dividers does not work for plywood form-work! The capacity of the foaming machine has to be taken into account, and depends on the batch size or continues production. Ensure the board is horizontal and lift the pipe. Record the added cement for future reference. The optimum water / cement ratio is also different for each type / brand of foaming agent. Ensure your mixing vessel is big enough to hold the volume you want to make, plus a bit extra for correction and saving it from spilling over the rim. Also concrete foam machine design has the advantages of high mixing quality, stable performance, low energy consumption, good sealing, and short discharging time. This can be tested by making some foam and leaving it in a glass and see how long it is before you see shrinkage and liquid on the bottom. The distribution of the bubble size seems also to have an influence on the MPa of the FC. There is a method of making FC where they put the foaming agent in with the mortar mix when it is all in a special high speed mixer. The concentrate and water mixture were mechanically agitated through a small nozzle to produce a foam and subjected to compressed air action at a high pressure. Adding super-plasticizers and accelerator to the mortar mix can also influence the bubble size and the distribution of the bubble size. Sits perfectly horizontal, and stays that way under the weight. Each manufacturer claims to have a superior product. FOAM AGENT ISOCEM S / BN 100% VEGETABLE, ISOCEM S / BN is the new product of the Isocem range, foaming agents for the production of Foam concrete. All your efforts can be ruined if this does not happen as it should be. Even more exciting than making the FC and can be just as tricky! You can use the same cone, but fill it in one go and do not tamper. The range of densities were 1500,1750 and 1800 kg/m3 . This will help in mixing of larger quantities. Having a foaming machine is probably the biggest hurdle in the process. A erated or Foamed Concrete This type of lightweight concrete is also known as gas concrete or foamed concrete, since it is developed by introducing large voids into the mortar mass or concrete. The slump of the concrete is measured by measuring the distance from the top of the slumped concrete to the level of the top of the slump cone. An ingenues way is to use a paint mixing tool, put a pipe over the shaft with a T connection at the top and a plug at the top. This is the most exciting part of the process! It is best to paint the plywood to stop it absorbing water. I have no idea of the concentration to use, experiment with it , and let me know please. You need to decide how much volume of FC you want to make. Varying from just adding another ingredient to the mortar during mixing and hoping for the best to really understanding what you are doing and getting it right. The first rule is that the form needs to be strong enough to hold the weight on the FC. This is achieved by the correct dilution rate and the foam making process. Check the mass of your sand, this can vary from 1.2 to 2.1. Depending on how well they are refined, protein based can have a shorter shelf life and can produce a smell in the FC. You can also keep it wet after it has set with sprinkling water onto it. You tested your foam and your mortar, now you need to verify that you have the correct density. We will also provide documentation along with this training and also discuss projects & experience in foamed concrete … If you have a project you want to share with us, I am happy to put this on the “FC projects” page. The advantage of FC is that the bubble “skin” contains water and becomes available for internal curing. As you now have discovered, making FC is like baking a pastry cake, not just an ordinary cake. The basic ingredients for the mortar are Portland cement, sand and water. The size depends on your building method and all the other factors that impact in the thickness of the wall. It also has to be done “gently” as not to collapse the foam. At the end of the third stage, the concrete is wiped off flush with the top of the mould. I have not seen a study that has taken this aspect into account, but my experience tell me it does. The range of w/c ratio used were 0.5, 0.45, 0.4, 0.35 and 0.3, while s/c was 1.0 for all mixes in this work. Cellular Concrete Mix Design. The density of the FC depends on how much foam you put in the mortar, there is a direct relationship. Use same manufacturer as the batch. Clean your equipment every time! Ensure you have clean water, usually drinking water is suitable. This dilution need to be precise and consistent for every batch if you want the same result. However their is a substance that is used to “strengthen” foam, Xanthan gum. The cone is placed on a hard non-absorbent horizontal surface. All other ingredients should be mixed in already, otherwise more mixing is needed and more foam collapse will occur. This is best done when it is set enough to holds its own shape and strong enough to withstand the force you may put on it when removing the form. Vermillion LLC and Associates is setting new standards for the Cellular Lightweight Concrete Industry. Bubbles can collapse because of reactions with other additives and the cement products we put in the mix. Now you are ready to pour! The best way is to inject the foam at the bottom of the vessel, close to the mixing implement if you make the mortar yourself. It is generally self levelling, self compacting and may be pumped. Dry Mix Method. Unit 6, Kennet Industrial Estate Check the claims the Foam agent manufacturer makes. © We here make the assumption that it is up to standard. Fine aggregate = fine aggregates + blast furnace slag +fly ash + … Mix design can be defined as the process of selecting suitable ingredients of concrete and determining their relative proportions with the object of producing concrete of certain minimum strength and durability as economically as possible. The W/C ratio to create the optimum strength FC with the used Foaming agent can vary. The mould for the test is in the form of an open top and bottom cone 30 cm height, bottom diameter 20 cm and top diameter 10 cm. “Board-formed Concrete” is the name for a process of patterning concrete that leaves a wood grain image on the finished face of the concrete. You need to be able to remove the form sideways from the FC. thick or more. Concrete Mix can be used Quikrete 80 lb. Retest to verify compliance with the range. How much it can withstand deformation depends on the surface modules and the surface tension. Using equipment designed and manufactured in-house... Propump Engineering have the available resources to offer a wide range of products and services to aid in the specification, production and supply of numerous foamed concrete materials from lightweight, thermally... Based in the UK Propump Engineering have exported foam generators, pump systems and chemicals all over the world. ( length (4M) of steel pipe is a simple way. The more foam we add the lighter it is, but also the weaker is becomes. I have tried it, and found that it did not made to foam “stand up” longer, but it may well have other beneficial qualities. The slump test is a measure of the consistency and work-ability of the concrete. Foam Concrete Mix Methods. Aircrete, Foamed concrete, Foamcrete, Foamed cement, Cellular lightweight concrete, Reduced density concrete, Lightweight concrete, Cellcrete, gasbeton, Foamkrete, air-cured lightweight concrete, gas concrete, insulated cellular lightweight concrete, insulating concrete, lightweight aggregate cellular concrete, low-density concrete, foamed mortar, mortar foam. This depends on the retarding effect and the ambient temperature. Small bubbles are stronger than big ones, the optimum size is 0.5 mm. Kent DA1 4QN As a result you end up with a mix that is lighter than “normal” concrete. Even if this is a whole house! This is also used as a food additive. Propump can offer a full mix design service based on many years of experience both in the field and in the test house. Trials: For Foam Concrete Mix –3 (Containing Cement, Blast Furnace Slag & Fine Aggregates& Glass Powder) Considering cement: FA (blast furnace slag ,fine aggregates , fly ash ,Glass powder) in 1:2.5 proportion. We leave this to the commercial specialists. This type is an alternative if you do not want to use the other types. The temperature of the water can have an influence on the result; keep it between 10 and 40 C.  If it is not ‘clean” than the organic matter can have a negative effect on the protein based foam agent quality, which would affect the FC mix formation. During the mix design for normal concrete the compressive strength required normally dictates the water/cement ratio and the workability gives an indication of the volume of water needed. ft. which develops a corresponding compressive strength range of 50 PSI - … Fax: +44 (0) 1322 429911 Foam concrete can be designed to have any density within the dry density range of 300–1850 kg/m3. Add enough foam to make a total of 45 gallons of AirCrete. During the mix design for normal concrete the compressive strength required normally dictates the water/cement ratio and the workability gives an indication of the volume of water needed. This site uses Akismet to reduce spam. Foam concrete, also known as Lightweight Cellular Concrete, Low Density Cellular Concrete, and other terms is defined as a cement-based slurry, with a minimum of 20% foam entrained into the plastic mortar. https://www.isoltech.it This is the only brand I found so far of this type that is why I mention it by name here. The Fc agents tend to have a retarding effect. Below is a overview of the properties for a FC mix without any additives that can improve some of these aspects. Dan Gerber: Dan Gerber has been in the concrete industry for 30 years. The deciding factor may be the weight you can lift and place them, and make a straight wall. The mortar is a cement mix with sand and water. The mixing occurred in a customized concrete mixer that was coupled with a progressing cavity pump. The biggest problem for the DIY is obtaining a small quantity of agent. Super Absorbent Polymer (SAP) is such a material and can be added to the FC mix. Both pervious & impervious foamed concrete are available in densities starting at 20PCF (wet cast), which has a typical compressive strength at 28 days of 50psi, up to 70PCF (wet cast), which has a typical compressive strength at 28 days of 1100psi. This slurry is further mixed with a synthetic aerated foam in a concrete mixing plant. Foamed concrete is a highly air entrained sand cement or cement only slurry with greater than 20% air by volume. Concrete Foundation Design, Installation, and Repair. Sand specified to be smaller than 2 mm may cost more. So far from the literature I found that the “dry” foaming method produces a finer bubble size. I always use a mould release agent for “normal” concrete on the form as the concrete can stick to the form and pull out. As the w/c ratio is extremely important to make a good FC is suggest you do some trials first. There are many different companies that make Portland cement up to standard to comply with Type I Portland Cement  specified in the British Standard (BS EN 197-1: 2000). When placing in excavations, foam concrete conforms to every sub grade contour. The concrete then slumps. As for baking a cake you need a good reliable oven. 80 lb. Crayford The dilution depends on the type and brand of the foam. Voids are typically injected through a chemical reaction, or … Did I mention to clean your foaming machine with (preferably) warm water! Before you make the foam you need to do some calculations. The typical density range is 20-60 lbs. Every unevenness in the wood will show up in your brick ! The quality of your foam influences the quality of the FC! Concrete Mix can be used for building or repairing foundation walls, sidewalks, curbs, steps and ramps and for setting posts. Ggbs gives the final foamed concrete a cohesive almost sticky consistency which whilst ideal for floor screeds, where a level or fall may be needed, it makes the material unsuitable for the applications such as the abandonment of long sewer runs where fluidity of the foamed concrete is the prime objective. If it is too stiff, than the foam will collapse. The consistency therefore is a measure of the water content of the concrete. Call Propump Engineering All rights reserved. This curing process will go on for years. Not “thin” enough put more foam in the mix. The process of mixing is carried out with proper control. The cheapest release agent is sugar water, but I am not sure what it does to FC. can be provided. / cu. Foam concrete mixer machine, also called concrete foaming machine or foam mixing machine, is a new and advanced concrete mixer, which is specially designed for foam concrete. The rules for curing FC are the same as for “normal” concrete, go to https://www.wikihow.com/Cure-Concrete. Be on the safe side and have more solution than you need for the batch. An important part in the process and it need to be done correctly, use the same method every time you make a batch of FC. You need to decide on the density FC you want to make. Learn how your comment data is processed. Fill the mould to the correct level every time. That's about 30" high in a standard 55 gallon drum. Some foaming agents may do this job better than others, but this is a subject for further research. (function($) {window.fnames = new Array(); window.ftypes = new Array();fnames[0]='EMAIL';ftypes[0]='email';fnames[1]='MMERGE1';ftypes[1]='text';}(jQuery));var $mcj = jQuery.noConflict(true); Lightweight Concrete Performance in Old Ships. Place the mould in such a position that you can easily take it apart. I never used anything less thick than 16 mm, also because the screws need a bit of thickness to hold and it needs to stay straight. The simplest way is to make bricks. Leave them to cure for at least a week, four weeks is better. What Happened to the Mix Design Chart? The fresh foam concrete comes from a process of continuously mixing foam and paste until an even mixture is obtained. Depending on the job, you can use foam concrete for applications such as partition walls, void filler, and thermal insulation for walls and roofs. Mixing the Foam Concrete longer and vigorously than needed destroys the bubbles. The “Ideal” mix would have at least 20 MPa at a density of 1000 Kg/m3, however the best results I have found in studies was 18 MPa and a density of 1200Kg/ m3. Equipment needed for the Slump Test: Slump test cone, non-porous base plate, measuring scale, temping rod. Fine silica sand of different sizes 0.6, 1.18 and 2 mm is often used. Some of the ingredients may not have fully reacted with its neighboring component due to the lack of water. The dirt around the mold wasn't solid enough to hold it firmly in place. In my opinion, the less bricks you need to use to build a wall the better it is. You cannot lift it straight up without damaging the FC if using a plywood mould. The simplest way to make a form for bricks is using plywood and screws. Concrete Mix consists of a uniformly blended, properly proportioned mixture of gravel, sand and Portland cement. If it is too “thin”, change your mind of what you are going to make as adding mortar in is not a good practice. But hang-on, this was the simple version! I made one myself using the (9L) pressurized pipe method. The water content controls and affects the cement content of the concrete. It is now common practice to use a super-plasticiser to improve the mortar. For suppliers of foaming agents go to Foaming agents. A study has shown that different agents require different W/C ratio’s for optimum strength. Well-Bonded body: Foam concrete forms a rigid, well-bonded body after hydrating. Knowing the total volume you need to achieve for the desired density is also a good measurement. +44 (0) 1322 429900. Quikrete 80 lb. Foam concrete pumps easily with relatively low pressures via hose over long distances. A good filter system helps. Sample mix proportions of foamed concrete are given in table- 1, 2 & 3. Fully automated large volume commercial machine see Agents and Equipment. When all the available water is used for the curing, the process stops. The desired bubble size is between 0.5 and 2 mm. Geofill Cellular Concrete products are lightweight materials specifically designed to provide engineers and contractors with a range of low density solutions for any number of … mix design, raw materials properties, mixing procedures, quality control, block moulds, ancillary equipment etc.) Once you decided what dilution you want to use, ensure that this is the same within 5% every time. The ratio of water and cement (w/c) is very important, this decides for a large part how “strong” your FC is going to be. I am looking for a receipt that created a “strong” foam. The methods used for designing normal concrete mix compositions cannot be used for designing foamed concrete mix compositions. This is the process of the FC hardening. https://www.facebook.com/InternationalFoamConcreteInstitute. In this investigation two foam concrete mixtures are produced with and without sand and attempts have been made for selecting the proportions of foam concrete mix … A simple FC with no additives is usually around 5-8 MPa with a density of 1000 Kg /m3. When designing foamed concrete a target casting density is … As a result you end up with a mix that is lighter than “normal” concrete. The mass, or density as we call it here, (weight per cubic meter) depends on how much foam is added to the mortar. This can be easily tested by filling an one liter container and weighing it. */, (We will only use your email address to send you our newsletter.). When the cement and water are well mixed, turn on the Little Dragon and add foam to the mixture. /* Add your own Mailchimp form style overrides in your site stylesheet or in this style block. Did I mention to clean up after pouring a batch? Last but not least keep it tidy, this avoids accidents. The air is created by the introduction of a preformed foam manufactured using Propump Engineering’s custom foaming agent (Propump 26), encapsulating bubbles of 0.3-1.5mm diameter. Now comes the best part, because you do not have to do too much. Because you can have variations in the quality of sand and the moisture content, how much water you put in, and other minor variations in your ingredients, the outcome of the mix need to be consistent to make consistent good FC. Protein based sodium and potassium salts of fatty acids (alkylcarboxylic acids), such as lauric and myristic acids. The optimum mix proportion was designed based on target density, w/c and s/c (sand to cement ratio) of lightweight foamed concrete. After the addition of water, or cement, remix the batch for 50 revolutions at mixing speed to insure adequate dispersion of the materials throughout the batch. Ensure you identify each sample. The measurement is taken directly after lifting the cone. Simultaneously, cement and water were mixed together using a specific mix design. This gives you the volume of the diluted agent. This cone is filled with fresh concrete in three stages. Make corrections as follows: Slump too low: Add water in measured amounts to bring the slump within the specified range. Each time, each layer is tamped 25 times with a 60 cm long bullet-nosed metal rod measuring 16 mm in diameter. Base Construction specializes in concrete foundation services of all kinds. The characteristics of the foam that make a “good” foamed concrete are: Stability, how long the foam keeps its bubbles. Foam properties This mix designed for pouring concrete 2 in. Do not let go dry! When making foam, the recommended “consistency” is 80 to 120 gram per liter, but I have seen publications where they used 45 g per liter. The dry mix method involves on-site production of the slurry (cement, fly ash and water). Curing FC is a chemical process! The combination of the strength and the insulation value makes FC an ideal building material. It exhibits good load bearing capacity and resistance to freeze thaw exposure. To make this easier, mark concentric circles on the board and place the cone in the center. It is inevitable that some of the foam will collapse during the mix, thus influences the density. You need to measure the consistency; one way of doing this is the slump test. The hose from the compressor need to be big enough in diameter, and not longer than needed. This page describes how to make FC and what influences the “quality”. The base mix of cement and sand is added to a unit. MIX DESIGN: There is at present, no guidance or standard method for proportioning foamed concrete, because the hardened density of foamed concrete depends on the saturation level in its pores. Foamed concrete typically consists of a slurry of cement or fly ash and sand and water, although some suppliers recommend pure cement and water with the foaming agent for very lightweight mixes. The most important issue for making the foam is the constant pressure that is delivered to the mixing chamber. With the introduction of VariMax™ Liquid Foam Concentrate the cellular concrete contractor has more options than ever before in creating exactly the correct cellular foam … Both 150mm (6”) and 100mm (4”) polystyrenecube moulds are kept in stock and can be supplied,on a next day basis, virtually anywhere in the UK. Specialized equipment of various size and production capacities can be used depending on project needs. The material is naturally self-leveling and fills the smallest voids, cavities and seams. You may find that the FC takes longer to set than normal concrete. The mould is lifted vertically upwards, so as not to disturb the concrete cone. This is a chemical reaction between aluminium and an acid. of foam concrete: (with foam agent GreenFroth and foam generator Fomm-PGM) Recommended weight of foam which is delivered to the mortar 5 g/l Density of foam concrete Sand Cement Water for concrete mix Water for foam Amount of foam (liter) Amount of foam … To produce consistent foam you need a reliable and controllable foaming method or machine. Hopefully we can come up with something that most of us can do in most countries at a reasonable cost. To avoid variable pressure and volume, the compressor capacity need to be big enough to keep up with the consumption when making foam! Often used for FC with a density higher than 1800 Kg/m3. The most important thing is to be consistent in your method. There are about 8 people selling various types. Try it and let me know. Risk of plastic shrinkage or settlement cracking is significantly lower than that of standard concrete. It is the same for FC. Cutting a brick to size for testing is not an accepted method as you can create hair cracks during cutting. For the advantages and dis-advantages of FC go to:  Why Foam Concrete is an ideal building material. Keep the poured form wet, or do not let it go dry, cover what you poured. Place 5 gallons of water into the concrete mixer. Add in any additive or colorant you wish to use in … There are FC “Brands” on the market that make the claim to be better than this. The quality of the foam is also influenced by the type of foam generator. The w/c depends on the plasticiser you are using. Most foaming agents collapse very quickly. Typically, specified characteristics are a wet cast density that’s +/- 5lb/cuft, and a minimum strength in psi at 28 days. The mortar should be flow able enough to be able to mix the foam into it. Can anyone help on this, or know a industrial chemist that is willing to help? Mix one 94lb bag of cement with 6 gallons (US) water.Put all the water in your container first and add the cement while you are mixing to avoid clumping. The production speed of the foam should be slightly faster than the mixing rate in batch production. The superplasticizer is available in dark brown aqueous solution. Again as per standard concretes the strength of foamed materials in the main can be attributed to the cement and water content for any given mix, unlike normal concretes however the type of foaming agent used will have a considerable bearing on the final strength, along with, to a certain extent, the type of fine aggregate used. If you know the volume per minute of your foaming machine and how much foam you need you can time the process. Making foam from household products such as soft soap or shampoo is not recommended if you can get hold of special FC foam. Topfoam foamed concrete has been specifically developed for void fill. Mixing the foam in the mortar is probably the last “additive” you want to put in the mix. Most brands will give you a guideline on a dilution for a given density. Registered in England: 2735521 The density of foam concrete … I let the foam cure for a few hours before attaching it to the post. Not all compressors are the same! The mould is clean and prepped with releasing agent. The bigger bubbles tend to collapse first when mixing it in with the mortar. Since the slump test is important, do not substitute a guess for an actual test. Email: info@propump.co.uk. Geofill LD and Geofill LD Pervious mix designs are designed to create a product with a low density and resultant relatively lower compressive strength (when compared to plain concrete). The mortar is a cement mix with sand and water. If you want to use a metal mould, check the FC equipment suppliers, go to Foam agent and equipment suppliers. Propump Engineering Ltd Your slump height will be too difficult to measure, measure the diameter of the “slump” instead. It probably is mostly around 1.6. When specifying lightweight foamed concrete, it’s best to leave the mix design up to the specialty contractor. For a picture go to  https://www.domegaia.com. Curing is a chemical process. With FC you may be able to mix the FC in a barrel that is placed above the moulds and have a hose attached to the bottom. Pumping the FC over great lengths and heights can destroy the bubbles as well. You can reach all the moulds comfortably when pouring. Internal curing can be assisted by the use of materials that absorb water quickly when whetted, but releases it slowly, or needs forces to suck the water out of the material. The mass, or density as we call it here, (weight per cubic meter) depends on how much foam is added to the mortar. Robert started his concrete career at a ready mix plant in 2005 loading ready-mix trucks, dispatching, and ordering material. Mixing the foam into the mortar is not easy as the mass of the foam and the mortar are very different. Some more on this, 8 pages and some interesting points. In this unit, the mix is blended with foam thoroughly. The material is a lightweight, free-flowing, self-compacting, and highly insulating material. Record the result for future reference. United Kingdom, Tel: +44 (0) 1322 429900 The pressure regulator need to deliver the same pressure all the time regardless if the compressor is running or has a fully pressurized tank. Foamed concrete is a highly workable, low density material incorporating up to 80% air. The dry method is also preferred as the water content is easier to control, and thus the effect it has on the mortar. Simply pour into place to the required level, Topfoam needs no compaction, has excellent insulating properties and can be delivered to site in conventional readymix concrete trucks. We use to have to moulds on a table, but we had to transfer the concrete from the wheel barrow onto the table.
