Compared to traditional concrete, aerated concrete is a relatively homogeneous material because it lacks the coarse aggregate, yet it exhibits wide variation in its characteristics. Aerated concrete is created using either chemical admixtures or mechanical foaming agents by trapping air in the matrix.
Types of aerated concrete: Based on the method of pore-formation it is classified into two types as follows: 1.Gas Concrete: Gas concrete is a mixture of water, cement, and very good aggregate with the final addition of a pore-forming chemical that produces air voids within the aqueous mixture at atmospheric pressure.

Autoclaved aerated concrete (AAC) has been commonly used as construction material by virtue of its functional performance [1–6], in particular, thermal insulation and energy efficiency [7–9]. AAC comprised of cement, fly ash, lime and fine-grained aggregates has been produced in Asia, Europe and Americas since it once turned into
Jun 26, 2010· Aerated concrete blocks are made from a combination of sand, lime, water, gypsum, and cement and provide structure, insulation, and fire and mold resistance. Blocks, lintels, wall panels, floor, and roof panels are some of the products made with aerated concrete blocks. Aerated concrete blocks are great green materials for wall construction that come with numerous advantages, but they also ...
Aerated concrete is relatively homogeneous when compared to normal concrete, as it does not contain coarse aggregate phase, yet shows vast variation in its properties. The properties of aerated concrete depend on its microstructure (void–paste system) and composition, which are influenced by the type of binder used, methods of pore-formation ...

Some concrete needs to be lighter and less dense and will require more air, while concrete used for very solid structures, like foundations, should have less. Sometimes the components of concrete will dictate how much air can be added to the mixture. To have full control over the aeration of your concrete, mix it yourself from scratch.
