经过强力捶捣的干硬性砂浆或素灰,具有高度的密实性和速凝性,用于刚性防水工程堵漏的效果,比掺各种防水剂的水泥胶浆更好,而且材料简单,操作方便。这里仅以平房灰打顶堵漏和地下室堵漏来简要说明操作要领。一、屋顶(混凝土屋顶、炉渣灰屋顶)裂缝处理。把裂缝凿成宽、深各4～5厘米的立壁槽沟,用压力水把槽沟内的灰屑冲刷干净,再反复刷水湿润槽壁,涂素水泥1～2道,使槽沟立壁上的每个麻坑内都沾着素浆。再用1:3干硬性水泥砂浆(砂要粗砂)把槽沟填满,用小锤砸捣,使砂浆的被捣面呈湿硬状。如果砂浆干硬度不足时,可以用干水泥面撒在摊开的砂浆面上,来解决水分过多的问题,拌匀后填进槽沟
After a hard-drying dry hard mortar or ash, with a high degree of compaction and quick-setting, for the effect of plugging rigid waterproof engineering, better than cement mortar mixed with a variety of waterproofing agent, and the material is simple, operation Convenience. Here only a brief description of the operation essentials is made with the cottage ash topping plugging and the basement plugging. First, the roof (concrete roof, ash ash roof) crack treatment. Dig the cracks into vertical and horizontal trenches with a width of 4 to 5 cm, flush the dust in the trenches with pressure water, and then brush the water to moisten the walls of the tank. Apply 1 to 2 coats of cement to make the trenches stand upright. Each pit is covered with plain pulp. Then use 1:3 dry hard cement mortar (sand to coarse sand) to fill the trench and use a small hammer to make the surface of the mortar wet. If the dry hardness of the mortar is not enough, you can use dry cement surface to spread on the spread mortar surface to solve the problem of excessive water, mix and fill in the groove
