水泥砂浆地面构造一般分为混凝土垫层和砂浆面层两部分。其传统施工工艺如下 :①混凝土垫层(基层)间隔时间t②基层清理③洒水湿润④涂刷素水泥浆结合层⑤做面层⑥养护。就这种施工工艺而言 ,关键是要处理好基层与面层的结合问题。工序②、③、④是专门解决这一问题的 ,但在实际施工中做好这几项难度非常大 ,不可能达到工序要求的质量标准。原因在于 ,其一混凝土基层清洁度只能定性 ,很难量化 ,不容易把握 ;其二基层施工表面要求粗糙 ,这 Cement mortar ground structure is generally divided into two parts of the concrete cushion and mortar surface. The traditional construction process is as follows: ① concrete cushion (grassroots) interval time t ② primary cleaning  ③ watering wet  ④ brushing water slurry combined layer  ⑤ do  ⑥ conservation. In this construction process, the key is to deal with the combination of grassroots and surface issues. Process ②, ③, ④ is designed to solve this problem, but in the actual construction of these several very difficult to do, it is impossible to meet the quality standards required by the process. The reason is that the cleanliness of a concrete base can only be qualitative, difficult to quantify, not easy to grasp; the second surface roughness of the base construction, which
