What is Foam Concrete?

foam-concrete (Medium)Foam concrete is a kind of porous concret, similar to aerated concrete. Foamed Concrete structures can be constructed easily and -unlike normal concrete – do not require compaction, levelling or vibrating. It’s outstanding resistance to water and frost, and supplies a high degree of both thermal and sound insulation.

In the froth generator the foaming agent is diluted in water to make a solution that is prefoaming and then the solution that is prefoaming is enlarged into froth with atmosphere. The bubbles are stable and capable to withstand the chemical and physical forces inflicted during mixing, setting and hardening of the concrete that is foamed.

It is necessary before making the froth to make the slurry first. The froth should be created and delivered right into the concrete mixer of the ready mix truck which has the slurry. All the froth should be permitted to mix into the slurry.

Advantages of foam concrete

  • Froth concrete possesses high drying shrinkage because of the lack of aggregates, i.e., up to 10 times greater than those found on standard weight concrete.
  • Foam concrete is self- selfcompacting and levelling, filling cavities, the lowest voids and seams within the place that is pouring.
  • Foam concrete is well suited to applications where fire is a hazard and extremely resistant.
    Evaluation have demonstrated that in addition to extended fire protection, the use of extreme heat, like a high energy flame held near the surface, will not cause the concrete to spall or burst as is the situation with regular weight concrete that was dense
  • Lightweight – will not inflict substantial loadings.
  • Exceptionally cost effective compared with other systems.

What’s the difference between cement grout and foam concrete?

Foam concrete is primarily composed of cement, water and atmosphere pores with filler (including PFA, sand etc.) without any class aggregates. The atmosphere pores are formed by agitating atmosphere with a foaming agent. For cement grout, it mostly includes water and cement.

Foam concrete is defined by have low density and low cost in comparison to standard concrete. The density of foam concrete is 400 – 1600 kg/m3. Thus, low dead load is enhanced by the low density and has wide-ranging uses when low loadings are needed. Froth concrete thus visits no lateral forces on adjoining structures and doesn’t need compacting. Furthermore, in addition, it shows great resistance to water and generates high degree of thermal and sound insulation.
