三合一地坪是由砂垫层、普通砖层和水泥砂浆面层组成的地坪。这种地坪发源于喜爱水泥地坪的用户,他们自发地在原有砖地坪上抹1:2.5水泥砂浆面层。对这种地坪我们作了一些实地考察,现将考察结果介绍如下,见表1 。情况分析:1.起砂的原因主要是,在抹水泥砂浆前,未洒水湿砖,抹后养护不好。2.地坪局部下沉的原因是,基层夯实不够,密实性差。断裂砖主要是地坪在砍柴时受局部

The three-in-one floor is a floor composed of sand cushion, ordinary brick and cement mortar. This type of floor originated from users who love concrete floors. They spontaneously applied 1:2.5 cement mortar to the original floor. We made some field visits to this floor. We will now introduce the results of the survey as follows. See Table 1. Situation analysis: 1. The main reason for sand formation is that before the cement mortar is used, the wet brick is not sprinkled, and the curing is not good after wiping. 2. The reason for the local subsidence of the floor is that the grass-roots level is not adequately tamped and the compactness is poor. Breaking bricks are mainly grounded when cutting wood
