Conctete Canvas

1、 What is concrete canvas

Concrete canvas is a soft cloth soaked in cement that undergoes a hydration reaction when exposed to water and hardens into a thin, waterproof, and fire-resistant durable concrete layer. The cement blanket is made of a three-dimensional fiber matrix woven from polyethylene and polypropylene filaments, and contains a specially formulated dry concrete mix. The main chemical components of calcium aluminate cement are Al2O3, CaO, SiO2, and Fe2O3. The bottom of the canvas is covered with a polyvinyl chloride (PVC) lining, ensuring that the concrete canvas is completely waterproof. During on-site construction, there is no need for any concrete mixing equipment. Simply water the concrete canvas or immerse it in water to cause hydration reaction. After solidification, fibers play a role in strengthening concrete and preventing cracking. Currently, the thickness of the cement blanket is 10mm
