水泥砂浆地面是建筑中应用最广的一种地面。但由于种种原因,常常会出现地面高低不平、起砂、裂缝等质量通病。为了解决这一问题,北京市第六建筑工程公司与北京市建筑材料科学研究所合作,研究成功了地面流平剂。这种流平剂是水泥砂浆在附加剂的作用下,获得高度的流动性,可以在几毫米厚度的情况下,将凹凸不平 Cement mortar floors are the most widely used type of ground in buildings. However, due to various reasons, there are often common problems such as unevenness of the ground, sand formation, and cracks. In order to solve this problem, the Beijing No. 6 Construction Engineering Company cooperated with the Beijing Institute of Building Materials Science and successfully studied the surface leveling agent. This leveling agent is a cement mortar under the effect of additives to obtain a high degree of fluidity, and can be uneven in the case of a few millimeters in thickness.
