Jul 17, 2017 · Lightweight concrete, also known as EPScrete (expanded polystyrene concrete), is a material widely used in the building of environmentally "green" homes. The substance is often made using small Styrofoam balls as a lightweight aggregate instead of the crushed stone that is used in regular concrete.

Mix Design. As in normal concretes the greater the air content the weaker the material, so with foamed concrete densities ranging from 200kg/m3 to 1900kg/m3 it is not surprising that the lower densities produce the lower strengths and at present even the densities at the upper limits do not produce strengths much above 15N/ mm2 .

When we need to cast concrete members of a building, we either use ready-mix concrete or prepare the concrete manually on site based on the mix design. Mix design is commonly referred to the mix proportion of concrete ingredients. The question is, how do we calculate concrete ingredients for different-ratio concrete?
The less water you use to mix the concrete (somewhat dry but workable) the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device. By measuring the mixing ratios you will have a consistent concrete mix throughout your entire project.

The methods used for designing normal concrete mix compositions cannot be used for designing foamed concrete mix compositions. 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.

A theoretical mix design is formulated and site trials are undertaken. The results from the site trials are used as a control for making the foamed concrete that is to be used for the work that is to be carried out. The next step is to make a cement slurry or a sand cement slurry that is appropriate for the mix design.
sign of poor quality or inappropriate mix design . Having 3D printing as the application technology in mind, achieving pumpable and self-stable foam concrete should be possible, but this approach has not been investigated thoroughly to date, and so, further research is needed.
Foamed concrete is a lightweight mixture of a cementitious binder, water, a stable preformed foam, and, possibly, fine aggregates. It possesses a cellular microstructure, which makes it a highly air-entrained system with typical physical and mechanical properties.
By Kaushal Kishore, Materials Engineer, Roorkee Foamed concrete, also called cellular light weight concrete is produced by the mixing of Portland cement, sand including or alone fly ash, water and preformed stable foam. The foam is produced with the help of a foam generator by using foaming agent.
The foam concrete machines are specially designed and manufactured to meet the specific requirements of high quality cellular concrete. The machine is composed of mixer, aerator, pump, water reservoir all controlled by electric panel board. The selected mix
foam [surfactant] or mix-foaming agents mixture into the cement and water slurry. As the concrete hardens, the bubbles disintegrate leaving air voids of similar sizes. Method B, known as Autoclaved Aerated Concrete [AAC] consists of a mix of lime, sand
Foamed concrete may have densities ranging from as low as 300kg/m3 to as high as 1800kg/m3. Foam concrete need minimum quantity of aggregate or sometimes no aggregates was used, hence it is lightweight and high flow ability. To mix a stable foam

Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
Porofoam foamed concrete can be supplied with or without coarse aggregate depending on the type and application. The stable bubble structure can be introduced into the mix in three ways: By blending a pre-formed foam into a
