很多建设单位认为纯水泥砂浆强度高,耐碰撞,要求在内墙面批档用纯水泥砂浆。其实,盲目用纯水泥砂浆批墙面并不好。纯水泥砂浆除了成本高、施工困难和工效低以外,而且施工质量也没有保证。产生这些问题的原因是:(1)水泥砂浆的和易性和保水性差,难以操作。(2)水泥砂浆凝结快,校正墙面平整及压光的时间短,往往墙面尚未压平抹光.水泥砂浆就已经结硬而无法操作了,不能大面积同时施工,同时降低了工效,并影响了墙面的光洁平整度(3)水泥砂浆收
Many construction companies believe that pure cement mortar has high strength and is resistant to collisions. It requires pure cement mortar to be used on the interior wall. In fact, blindly using pure cement mortar to approve walls is not good. In addition to high cost, construction difficulties, and low work efficiency, pure cement mortar has no guarantee of construction quality. The reasons for these problems are: (1) The cement mortar has poor workability and water retention and is difficult to handle. (2) The cement mortar is quickly set up, the time for correcting the wall surface and the calendering time is short, and the wall surface is not flattened and polished. The cement mortar has already been hardened and cannot be operated, and the large-area construction cannot be simultaneously performed, and at the same time, the work efficiency is reduced. Affected the smoothness of the wall surface (3) cement mortar collection
