3. Green and energy-saving: 95% less material consumption than traditional concrete, low alkali content, low erosion rate, minimal ecological impact, in line with sustainable concepts.
4. Durability and damage resistance: The fiber-reinforced structure is crack resistant and impact resistant, resistant to chemical corrosion, wind, rain, and ultraviolet rays, and has a durability of over 120 years.
Products Introduction：
Cement Cloth is an innovative engineering material composed of glass fiber woven cloth soaked in a special cement mixture. It subverts the traditional form and usage of concrete materials, presenting a soft and plastic state when not in contact with moisture, like fabric that can be freely curled, cut, and transported; And once it meets water, it will quickly undergo a chemical reaction, gradually harden and form a concrete like structure with high strength and durability. This material combines the flexibility of fabric with the strength of concrete, bringing a new solution for engineering construction.
Product Features：
1. Convenient and efficient construction: When not wet, the texture is soft and can be easily curled and cut according to construction needs. The transportation and storage process is very convenient, without the need for large equipment assistance. During construction, only water spraying is needed to initiate the curing process, eliminating the tedious steps of traditional concrete mixing and pouring, greatly reducing labor input and construction time, and enabling rapid construction even in complex terrains.
2. Rapid hardening molding: It has a short adjustable time after encountering water, and its shape can be corrected within 2 hours to meet the construction accuracy requirements. Within 24 hours, 80% of the final strength can be achieved. If an accelerator is added, the hardening speed can be further improved, making it particularly suitable for engineering projects with strict schedule requirements and effectively shortening the overall project cycle.
3. Green, environmentally friendly and energy-saving: Compared with traditional concrete, cement cloth can save 95% of materials in production and use, greatly reducing resource consumption. Its low alkali content has minimal impact on the surrounding soil, water quality, and other ecological environment during use, and its low erosion rate can reduce dust and waste pollution during construction, fully in line with the current concept of sustainable development.
4. Strong durability and damage resistance: The use of fiber-reinforced structure effectively enhances the material's crack resistance and impact resistance, and can withstand a certain degree of external impact and vibration. At the same time, it also has excellent chemical corrosion resistance, can resist the erosion of various chemical substances, and is resistant to wind, rain, and UV aging. It can maintain stable performance in various harsh environments and has a service life of over 120 years.
