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 typical density range is 20-60 lbs. Fully automated large volume commercial machine see Agents and Equipment. When all the available water is used for the curing, the process stops. Small (0.5 mm) homogenous bubble size makes stronger FC. All other ingredients should be mixed in already, otherwise more mixing is needed and more foam collapse will occur. This is the most exciting part of the process! Propump Engineering Ltd Not all compressors are the same! Bubbles can collapse because of reactions with other additives and the cement products we put in the mix. Once you decided what dilution you want to use, ensure that this is the same within 5% every time. Keep the poured form wet, or do not let it go dry, cover what you poured. The range of densities were 1500,1750 and 1800 kg/m3 . “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. Concrete Mix consists of a uniformly blended, properly proportioned mixture of gravel, sand and Portland cement. 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. +44 (0) 1322 429900. The optimum water / cement ratio is also different for each type / brand of foaming agent. There are FC “Brands” on the market that make the claim to be better than this. document.write(new Date().getFullYear()); Propump Engineering Ltd. This can be your own home project, or a bigger event such as a whole house. Ensure you have clean water, usually drinking water is suitable. 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. Mixing the foam into the mortar is not easy as the mass of the foam and the mortar are very different. I have not seen a study that has taken this aspect into account, but my experience tell me it does. At the end of the third stage, the concrete is wiped off flush with the top of the mould. When designing foamed concrete a target casting density is … The type of foam generator has a large influence of the bubble size as well. There is a dry and a wet method to make foam, the dry method produces smaller bubbles. This can vary from a couple of hours to more than 3 days. When placing in excavations, foam concrete conforms to every sub grade contour. Ensure the board is horizontal and lift the pipe. As you now have discovered, making FC is like baking a pastry cake, not just an ordinary cake. Every unevenness in the wood will show up in your brick ! Fax: +44 (0) 1322 429911 The cone is placed on a hard non-absorbent horizontal surface. Good results can be achieves for bubble sizes between .05  and 1 mm and preferably the majority of a similar small size. Leave them to cure for at least a week, four weeks is better. 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. Foam Concrete Mix Design [8jlkjyv3y8n5]. Fill the mould to the correct level every time. Below is a overview of the properties for a FC mix without any additives that can improve some of these aspects. If you make blocks cover them until you take them out of the mould, then wrap the blocks in cling wrap. Foamed concrete is a highly air entrained sand cement or cement only slurry with greater than 20% air by volume. It probably is mostly around 1.6. All your efforts can be ruined if this does not happen as it should be. Also concrete foam machine design has the advantages of high mixing quality, stable performance, low energy consumption, good sealing, and short discharging time. This will help in mixing of larger quantities. The advantage of FC is that the bubble “skin” contains water and becomes available for internal curing. This cone is filled with fresh concrete in three stages. This gives you the volume of the diluted agent. 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.
