In terms of production and processability, foamed cement can be produced not only in a variety of products in the factory, but also on-site construction, directly cast into roofs, floors and walls, and can be sawed, planed, nailed, drilled, etc. Processing. Environmental protection, raw materials required for foaming cement are cement and foaming agent, foaming agent is neutral, does not contain benzene, formaldehyde and other harmful substances, avoiding environmental pollution and fire hazards. Economical, low overall cost. Fire resistance, because the main raw material of foamed cement is cement, cement is completely fireproof inorganic material.
