Erosion Control Concrete Canvas
Composite cement blanket is an innovative composite material that combines the flexibility of textiles with the firmness of cement, and can be quickly laid and hardened into a durable concrete layer.
High construction efficiency: No professional equipment is required. It can be laid by a single person and is 10 times faster than traditional concrete. Fast forming, available in rolls or bulk, convenient for transportation, loading and unloading, and installation.
Environmental protection and energy conservation: Reduce material waste and lower carbon emissions by over 90% compared to traditional processes.
Strong flexibility: It can be cut to adapt to complex terrains and even used for vertical suspension.
Durability: Resistant to freeze-thaw cycles, corrosion, wear, erosion, seawater and sewage corrosion
The service life of UV aging resistance can reach 50 years.
The product advantages of Erosion Control Concrete Canvas are mainly reflected in its rapid construction, flexible adaptability, environmental protection and energy conservation, and multi-functionality, etc. Specifically, they can be summarized as the following core characteristics:
1. The construction efficiency is extremely high
- Ready to use upon laying: After spreading, water it and it will harden immediately. It reaches its usable strength within 24 hours, which is more than 10 times faster than traditional concrete construction (requiring 7 to 28 days of curing).
- No complex equipment required: It can be operated by a single person, eliminating the need for mixing, pouring, vibration and other steps. It is especially suitable for remote areas without electricity or mechanical support.
All-weather operation: Unaffected by adverse weather conditions such as rain, snow and low temperatures, it can quickly respond to emergency engineering needs (such as flood control and rescue).
2. Flexibility and adaptability
- Cropped and bendable: It can be cut into any shape to adapt to complex terrains such as slopes, ditches, and irregular structures, and can even be used for vertical suspension.
- ightweight transportation: The weight per square meter is only about 15-25 kilograms (with different thicknesses), and the roll form is convenient for vehicle or manual handling.
Seamless forming: After hardening, a continuous concrete layer is formed without seams, avoiding the risk of leakage (such as anti-seepage in water conservancy projects).
3. Environmental Protection and Sustainability
- Reduce material waste: Cut as needed, precisely control the amount of cement used, and avoid excessive pouring of traditional concrete and the generation of waste.
- Low carbon emissions: Carbon emissions during the production and usage process are reduced by over 90% compared to traditional concrete (no need for heavy machinery or long-distance transportation).
- High durability: Resistant to freeze-thaw cycles and corrosion, with a service life of up to 50 years, reducing later maintenance and resource consumption.
4. Multi-functional application scenarios
- Rapid emergency response: Building temporary roads, flood walls or shelters during disasters (such as in earthquake and flood rescue operations).
- Low-cost infrastructure: Suitable for reinforcing simple roads and canals in remote areas, reducing labor and logistics costs.
Special environment construction: Provide efficient solutions in areas such as steep slopes and narrow Spaces where traditional concrete is difficult to cover.
5. Economic advantage
- Low comprehensive cost: Although the unit price of materials is relatively high (about 200-500 yuan per square meter), by eliminating equipment rental, labor and maintenance costs, the overall cost can be reduced by 30% to 50%.
- Shorten the construction period: The project cycle is significantly compressed, reducing indirect losses caused by project delays (such as traffic control and downtime costs).
6. Superior technical performance
- High strength: The compressive strength reaches 20-50 mpa (equivalent to C20-C50 concrete), and the tensile strength is 10 times that of traditional concrete.
- Waterproof and anti-seepage: Surface waterproof coating + dense structure after hardening, suitable for anti-seepage projects such as water tanks and drainage systems.
- Fireproof and heat-resistant: Some models can withstand temperatures up to 1200℃, meeting the requirements of fire protection and industrial scenarios.
