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 *0mm

 

2、Advantages of concrete canvas products & The main characteristics of concrete canvas

 

1) Easy to use concrete canvas

Concrete canvas can be provided in bulk in large rolls. It can also be provided in rolls, facilitating manual loading and unloading and transportation, without the need for large lifting machinery. Concrete is prepared according to scientific proportions, without the need for on-site preparation and without excessive hydration problems. Whether underwater or in seawater, cement blankets can solidify and form.

2) Concrete Canvas Rapid Solidification Forming of Concrete Canvas

Once the concrete canvas undergoes hydration reaction after watering, it can still undergo necessary processing on the size and shape of the cement blanket within 2 hours. Within *4 hours, it can harden to *0% of its strength. It is also possible to achieve rapid or delayed solidification using special formulas according to the special requirements of users.

3) Concrete canvas is environmentally friendly

Concrete canvas is a low-quality low-carbon technology that uses up to *5% less materials than commonly used concrete in many applications. Its alkali content is limited and its erosion rate is very low, so its impact on the local ecology is minimal.

4) Flexibility of concrete canvas application

Concrete canvas has good drapability and can adhere to the complex shapes of the covered object surface, even forming a hyperbolic shape. The cement blanket before solidification can be cut or cut freely with ordinary hand tools.

5) Concrete canvas material with high strength

The fibers in concrete canvas enhance material strength, prevent cracking, and absorb impact energy to form a stable failure mode.

6) Long term durability of concrete canvas

Concrete canvas has good chemical resistance, resistance to wind and rain erosion, and will not undergo UV degradation under sunlight.

7) Waterproofing characteristics of concrete canvas

The bottom of the concrete canvas is lined with polyvinyl chloride (PVC) to make it completely waterproof and enhance the material's chemical resistance.

8) Fire resistance characteristics of concrete canvas

Concrete canvas does not support combustion and has good flame retardant properties. When caught on fire, the smoke is very small and the emission of hazardous gases is minimal. The cement blanket has reached the B-s1 and d0 levels of the European building material flame retardant standards.
