3. Environmentally friendly and efficient: The material usage is 95% less than traditional concrete, and there is no dust or noise pollution during construction. It can be cut arbitrarily to avoid waste and belongs to low-carbon environmental protection technology.
Product Introduction:
Concrete Impregnated Fabric is an innovative geosynthetic material that combines traditional concrete materials with textile technology. Its core characteristic is that it is in the form of a soft cloth when it leaves the factory, and after encountering water, it hardens into a high-strength concrete layer through hydration reaction. It has waterproof, fireproof, durable and other properties, and is widely used in construction, water conservancy, transportation, ecological restoration and other fields.
Characteristics and advantages
1. Convenient construction: provided in a roll shape, convenient for manual handling and transportation, without the need for large mechanical assistance. The laying process is simple, only watering is needed to trigger hydration reaction, and it can quickly solidify into a concrete layer. It can be constructed in various complex terrains and can be cut according to needs, greatly saving manpower and construction time.
2. Efficient and durable: The concrete layer formed by the fusion of three-dimensional fiber blanket and composite concrete dry powder material after water hardening has high strength and toughness, which can effectively prevent water infiltration and fire spread, and has a long service life.
3. Environmental Protection and Conservation: As a low-carbon technology, the material usage is reduced by up to 95% compared to traditional concrete. No concrete mixing equipment is required during construction, reducing dust and noise pollution. And it can be curled and cut freely to avoid material waste.
4. Controllable solidification: Through a special formula, rapid or delayed solidification can be achieved. Within 2 hours after watering and hydration reaction, its size and shape can still be processed, and it can harden to 80% strength within 24 hours, which can meet different construction needs.
5. Strong stability: Made of high-strength materials with good tensile and compressive properties, it has low requirements for the foundation and can work stably in various harsh environments, providing solid support for engineering structures.
6. Strong corrosion resistance: Made of corrosion-resistant materials, it can resist the erosion of harsh environments such as acid and alkali, salt spray, etc., and is not easily affected by chemical substances, thus maintaining good performance and extending service life.
7. Flexible application: It has good drape and can be laid according to the complex shape of the covered object surface, even forming a hyperbolic shape, suitable for the construction of various irregular structures.
