The scientific name of cement blanket is concrete cloth, which is a soft cloth impregnated with cement. When it comes into contact with water, it undergoes hydration reaction and hardens into a very thin waterproof and fire-resistant durable concrete layer.

The concrete canvas adopts a three-dimensional fiber composite structure (3D fiber matrix) woven from polyethylene and polypropylene filaments, containing a special formula of dry concrete mix. The main chemical component of calcium aluminate cement is Al2O3, CaO, SiO2, Fe2O3。 The bottom of the canvas is covered with a polyvinyl chloride (PVC) backing.
