Powder-type elastic waterproof coating composition containing micro-cement
This technology relates to a micro-cement waterproofing composition and a waterproofing method that combines Portland cement, ready-mixed mortar, and micro-cement with waterproofing agents and reinforcing fibers.
Conventional coating-type waterproofing materials often lacked crack-bridging ability and long-term durability, making them susceptible to leaks through micro-cracks.
To address this, our technology combines fine-particle micro-cement with ultra-rapid hardening ready-mixed mortar and reinforcing fibers to create a dense waterproof layer with superior elasticity and crack resistance.
Key Features:
- Waterproofing composition comprising 100 parts by weight of Portland cement, 100 parts by weight of ready-mixed mortar, and 10 parts by weight of micro-cement
- Includes 0.5 parts by weight of waterproofing agent, 0.5 parts by weight of reinforcing fibers, 0.1 parts by weight of viscosity modifier, and 0.05 parts by weight of hardening retarder
- Ready-mixed mortar is formulated with ultra-rapid hardening cement and dry sand in a weight ratio of 100:80 to 230 to provide ultra-rapid hardening properties
- Micro-cement features a fineness of 6500–7000 cm²/g and an average particle size of 3–5㎛ to enhance waterproofing performance
