Foamed Concrete - an overview ScienceDirect Topics

The air can be introduced into a mortar or concrete mix using two principal methods. First, a preformed foam from a foam generator can be mixed with other constituents in a normal mixer or a readymixed concrete truck. Second, a synthetic- or protein-based foam-producing admixture can be mixed with the other mix constituents in a high-shear mixer.

Cellular Concrete Topic

Oct 01, 2020  Cellular concrete is a mixture of cement, water, and preformed foam. The purpose of the foam is to supply a mechanism by which a relatively high proportion of stable air voids can be induced into the mixture and produce a cellular or porous solid upon curing of the mixture. When cellular concrete hardens, it has an oven-dry density of 50 lb/ft3 (.8 t/m3)or less.
