What is Cellular Concrete?
Cellular concrete, also known as aerated concrete or foam concrete, is a versatile construction material characterized by its cellular structure. It is produced by blending a cementitious mixture with a foaming agent, resulting in a matrix filled with countless air voids or cells. These cells impart cellular concrete with its unique lightweight properties while maintaining excellent compressive strength.
How is Cellular Concrete Produced?
The production of cellular concrete involves a meticulous process that combines various components. First, a specialized foaming agent is introduced into a cementitious mixture, often consisting of cement, sand, water, and other additives. This foaming agent generates stable bubbles within the mixture, creating a homogeneous foam. The foam is then mixed with the cementitious matrix, forming a uniform cellular concrete mixture. Finally, the mixture is poured or cast into molds, where it sets and cures to achieve the desired structural integrity.
