Fiber-Reinforced Cement Board Flat External Wall Partition Wall Cement Board 1220*2440mm revolutionizes exterior cladding and interior partitioning with advanced material science. This engineered composite combines Type III high-density Portland cement with cross-layered cellulose fibers and mineralized quartz particles, creating a dimensionally stable panel specifically designed for load-bearing applications. The board's unique manufacturing process involves high-pressure steam curing at 180°C, achieving 94% hydration completeness for maximum structural performance.
