The internationally pioneering "internal curing + self-healing" dual-effect technology system: High water retention and release components continuously compensate for humidity gradient losses through internal curing, significantly reducing the risks of autogenous shrinkage and early cracking; nano-active minerals and complex crystalline components activate upon contact with water to generate dense fillers, actively repairing micro-cracks and restoring structural impermeability and mechanical properties. It is specifically designed for hydraulic and underground projects with extremely high requirements for long-term impermeability and crack prevention, such as high-altitude water diversion tunnels, canyon reservoir dams, and subsea tunnels.
The hydration heat reduction rate is ≥50% at 8 hours and ≥30% at 24 hours; the self-shrinkage rate ratio is ≤60% at 7 days and ≤85% at 28 days; the self-healing rate of cracks (≤0.50mm) is ≥90% at 28 days; the impermeability grade is ≥W16; the frost resistance grade is ≥F250; the compressive strength ratio at 28 days is ≥95%
