水东水电站由于受工期制约,经反复试验,研制成功了一种缓凝型混凝土表面处理剂。它可使混凝土表面缓凝,在混凝土终凝后的24h内,用约3kg/cm~2低压水就可轻易冲掉其乳皮,获得清晰的混凝土毛面。这种处理剂对混凝土各项力学指标均无不利影响;施工工艺极为简单,只需在混凝土浇筑后,在混凝土表面手撒该处理剂,尔后用低压水冲洗,就完成成整个层面处理过程。在水东水电站工程建设中采用了这种处理剂,取得较好的效果。
Due to the constraints of construction period, Shuidong Hydropower Station has successfully developed a retarding concrete surface treatment agent after repeated tests. It makes the concrete surface retarded, within 24h after the concrete final setting, with about 3kg / cm ~ 2 low-pressure water can easily wash away its milk, get a clear concrete matte. The treatment agent has no adverse effect on various mechanical indexes of concrete. The construction process is extremely simple. After the concrete is poured, the agent is hand-sprinkled on the concrete surface and then rinsed with low-pressure water to complete the entire layer treatment process. In the hydropower project construction using this treatment agent, and achieved good results.
