Foamed cement can be divided into physical foaming and chemical foaming according to different production methods.
Physical foaming: The foaming agent is prepared into a foam by mechanical equipment, and then the foam is added to a slurry made of cement-based cementitious material, aggregate, admixture, admixture and water, and stirred and poured. Insulation board formed by molding and curing (hereinafter referred to as foamed cement insulation board).
Chemical foaming: the foaming agent is added to a slurry made of cement-based cementitious materials, aggregates, admixtures, admixtures and water, and mixed and stirred to make a chemical reaction in the mold. The inside of the slurry produces closed pores, which are cured and cut into heat-insulating sheets.
