| 摘要 | Concrete lining slabs of long-distance water conveyance projects in northern China are susceptible to freeze-thaw erosion, which places higher requirements on the performance of repair materials for eroded areas, such as frost resistance, adhesion, coating penetration depth, water absorption ratio, and durability. Performance tests were conducted on existing repair materials, and the results showed that: XYPEX exhibits better performance compared to other materials; the high-performance ultra-nano silane impregnant has outstanding performance; and the composite coating demonstrates excellent comprehensive performance. The composite material modified with nano-SiO2 has further improved strength and durability. |
