The cement blanket, also known as the cement canvas, is a three-dimensional fiber composite structure made of polyethylene and polypropylene fiber filaments. It is a special impregnated soft cement cloth. When exposed to water, the hydration reaction occurs, and rapid hardening takes place. It can be cut and shaped as desired before solidification, providing anti-cracking, fire resistance, and anti-corrosion properties. It can be used in extremely hot and cold conditions, with a simple and short construction period, and is environmentally friendly with low carbon emissions.
