Cement foaming agent, also known as foaming concrete foaming agent, refers to an admixture that can reduce the surface tension of liquid and generate a large amount of uniform and stable foam for the production of foamed concrete. Foaming agent is a kind of substance that can make its aqueous solution generate a large amount of foam when the mechanical force is introduced into the air. This kind of substance is a surfactant or a surface active substance. The essence of the foaming agent is its surface activity. Without surface activity, it cannot foam, and it cannot become a foaming agent. Surface activity is the core of foaming.
