岳城水库溢洪道混凝土面板的修补处理

The repair of concrete pavement of the spillway in Yuecheng Reservoir

介绍了SPC聚合物水泥砂浆和PT胶泥在岳城水库溢洪道面板混凝土修补处理中应用情况。SPC砂浆是一种新型的混凝土表面修补材料，它是以少量有机聚合物掺入到新拌水泥砂浆中形成的复合胶凝材料，但为了达到良好的修补效果，应严格按照施工工艺进行施工。PT胶泥具有高温不流淌、低温柔性好、延伸性能和耐老化性能良好等特点，是一种较理想的混凝土面板伸缩缝嵌缝材料。

This paper introduces the utilization of SPC polymer modifying mortar and PT colloid paste for the repair of the spillway concrete pavement of Yuecheng Reservoir. The SPC mortar is a new type of material suitable for the repair of concrete surface, it is made of a few amount of organic polymer latex mixed with fresh cement mortar. In order to get a good result, it needs a very strict processing operation and meets the technical requirement during construction. The PT colloid paste has a good performance on tensibility and durability, it can keep flexible in low temperature and sticky in high temperature, and it is useful for the sealing of concrete pavement joint.
