| 摘 要： | 含砂高速水流对水工建筑物过流面混凝土的冲磨破坏是水电工程建设和运行中的疑难问题。在优选的胺类—环氧树脂固化体系抗冲磨材料配方中，加入增韧剂GXY后，制备出具有“海岛结构”的合金增韧型双组分抗冲磨材料，常温、低温（0℃左右）可固化，粘结、抗压、抗冲磨强度等力学性能高，配制、施工操作简便、适应性强、能在潮湿面施工，是一种性能优良的用于水工建筑物过流面防护和缺陷修补的材料。 |
| 关 键 词： | 混凝土缺陷修补 抗冲耐磨材料 海岛结构 过流面 |

| Abstract: | The scouring and abrasion damage on overflow concrete surface of hydraulic structure by sediment -loaded and high speed-up flow is a problem for construction and operation of hydropower projects. In anti-scouring -and-abrasion material of solidification system amine-epoxy,after adding toughening agent GXY,the two-component abrasion resistant material possessing "island structure" with alloy toughening effect can be made,which can be consoli-dated at normal and low temperature,and has superior features of co... |
| Keywords: | concrete defect repairing anti-scouring-and abrasion material "island structure" overflowing surface |
