Cement Blanket
Product Introduction
The cement blanket is an innovative composite material combining the flexibility of textiles with the durability of concrete. It typically consists of three layers: a bottom porous water-absorbing fabric ensuring uniform water penetration, a middle layer of dry concrete mixture that solidifies through hydration, and a top three-dimensional fiber-reinforced framework enhancing tensile strength. Its key advantage is its flexibility as a rolled material during transport, hardening after laying and watering, significantly simplifying traditional concrete construction processes.
Performance Characteristics
• Excellent mechanical properties, including high strength, impact resistance, and flexible crack resistance.
• Outstanding resistance to environmental corrosion, erosion, and wear.
• Convenient and efficient construction with eco-friendly and energy-saving benefits.
Function and Use
• Water Conservancy Projects:
o River dam slope protection and anti-seepage reinforcement of drainage ditches/canals.
o Fishpond slope protection and anti-seepage for artificial lakes.
o Temporary diversion channels and emergency reinforcement of flood control embankments.
• Transportation Infrastructure:
o Highway/railway slope protection and shoulder stabilization.
o Mine tunnel support and water diversion ditch lining.
• Ecological Restoration:
o Soil and water erosion control (with optional grass planting).
o Sand dune stabilization and greening material for steep slopes.
