Concrete Curing Hessian Cloth
1. Rapid construction: No need to mix concrete on site, it can harden by watering after laying, and can reach 80% strength within 24 hours.
2. Lightweight and easy to transport: In the form of rolls, the weight is only 1/5 of traditional concrete, making it easy to handle and store.
3. Environmental protection and energy conservation: reduce cement waste, lower carbon emissions, and the construction process does not require large machinery.
4. Strong adaptability: It can adapt to complex terrain and is suitable for areas where traditional concrete construction is difficult, such as slopes and curved surfaces.
5. Good durability: compression resistance, frost resistance, chemical corrosion resistance, long service life.
Product Introduction:
Concrete Curing Hessian Cloth is a new type of composite material composed of a three-dimensional fiber matrix (usually a flexible fabric) and a specially formulated dry mix cement. When in use, simply water it to hydrate and it will quickly harden into a sturdy concrete layer. It combines the flexibility of textiles with the durability of concrete, and is known as the 'rollable concrete'.
characteristic
1. Excellent physical performance
High strength: With a compressive strength of 20-40MPa, it can withstand vehicle loads and soil pressure.
Wear resistant and impact resistant: The fiber skeleton is embedded with hard particles such as quartz sand to resist mechanical wear and external impact.
2. Wide environmental adaptability
Waterproof and anti-seepage: The upper and lower waterproof membranes form a dual barrier with the fiber structure, suitable for underwater or humid environments.
Fireproof and flame retardant: Passed A-level fireproof certification, it does not burn or produce toxic gases in a fire.
Corrosion resistance: resistant to acid, alkali, salt spray, and microbial erosion, suitable for chemical and coastal areas.
3. Construction flexibility
Trimmable splicing: Supports cutting of any size, with cement mortar sealing at the overlap and U-shaped nail reinforcement to ensure sealing.
Quick repair: Local damage can be directly covered with a new blanket, and after watering and curing, the overall integrity can be restored.

Cement blankets have redefined the application boundaries of concrete through the integration of material science and engineering technology. Its "flexible hardening" characteristic not only solves the efficiency, cost, and environmental problems in traditional concrete construction, but also demonstrates great potential in emerging fields such as emergency response and ecological restoration. With the continuous optimization of technology, cement blankets are expected to become one of the core materials for smart cities, green infrastructure, and disaster management.
