1出现的问题2015年5月中旬,我公司接到一农村用户电话,反映使用的P·C32.5R水泥加入水后不吸水,水泥无法贴瓷砖。农村贴瓷砖方法一般为:将一定量的水泥倒一桶内,倒满水,把瓷砖放入桶内,浸泡一段时间后,直接将瓷砖贴到墙上。所谓不吸水,就是倒入桶内的水,只与表面一层的水泥发生水化反应,而桶下部的水泥仍是干的。 1 Problems Appeared In mid-May, 2015, our company received a telephone call from a rural user, reflecting that the P.C32.5R cement used did not absorb water after it was added to water, and cement could not be tiled. The method of tiling in rural areas is generally: pour a certain amount of cement into a bucket, fill it with water, put the tiles into the bucket, and after immersing for a period of time, directly apply the tiles to the wall. The so-called non-absorbing water is the water poured into the barrel, and only hydration reaction occurs with the cement on the surface, and the cement in the lower part of the barrel is still dry.
