Fast-Setting Concrete Cloth
1. Rapid construction
After laying, it solidifies by watering, sets within 24 hours, and can reach its strength within 3 days, which is more than 10 times faster than traditional concrete. It is suitable for emergency repairs and projects.
2. Save labor and materials
No need for templates or mixing equipment, 2 people can operate, reducing labor costs; High material utilization and minimal waste.
3. Lightweight and flexible
Roll packaging, convenient transportation; Can be trimmed, bent, and adapted to complex terrain.
4. High strength and durability
Fiber reinforced crack resistance, corrosion resistance, UV resistance, and long service life.
Product Introduction:
Fast-Setting Concrete Cloth is an innovative geosynthetic material that combines cement-based materials with fiber weaving technology. The core principle is to uniformly impregnate dry concrete mixture (including cement, sand, additives, etc.) into a three-dimensional fiber skeleton through a special process, forming a flexible blanket like structure that can be curled. After encountering water, dry concrete undergoes hydration reaction and can harden into a high-strength, waterproof and fireproof concrete layer within 24 hours, combining the durability of traditional concrete with the flexibility of textile materials.
Product characteristics
1. Easy to use: It can be provided in bulk or rolled up, making it convenient for manual loading, unloading, and transportation without the need for large lifting machinery. Concrete is prepared according to scientific proportions and does not require on-site preparation.
2. Rapid solidification molding: After watering and hydration reaction, its size and shape can still be processed within 2 hours, and it can harden to 80% strength within 24 hours. It can also achieve rapid solidification or delayed solidification through special formulas.
3. Environmentally friendly: It is a low-quality and low-carbon technology that uses 95% less materials than commonly used concrete in many applications. The alkali content is limited, the erosion rate is very low, and the impact on the local ecology is minimal.
4. Flexible application: It has good drape and can conform to the complex shape of the covered object surface, even forming a hyperbolic shape. Before solidification, it can be cut or trimmed freely with ordinary hand tools.
5. High material strength: Fibers play a role in enhancing material strength, preventing cracking, and absorbing impact energy to form failure modes.
6. Long term durability: It has good chemical resistance, resistance to wind and rain erosion, and will not undergo ultraviolet degradation even in sunlight.
7. Good waterproof performance: The bottom has a waterproof layer, making it completely waterproof and enhancing the material's chemical resistance.
