水泥砂浆为多成分非匀质体,由于原材料和内部结构的局限,其内部存在大量的毛细孔和微细裂纹,变形位能很低。而且由于须经施工现场二次加工,其成型质量还受到施工过程中的计量准确程度、搅拌均匀性、振捣密实程度、施工气候条件、养护条件等诸多因素的影响,因此水泥砂浆存?.. Cement mortar is a multi-component non-homogeneous body, due to the limitations of the raw materials and internal structure, there are a large number of pores and fine cracks in the interior, the deformation potential can be very low. Due to the secondary processing on the construction site, the forming quality is also affected by many factors such as the accuracy of measurement, the uniformity of mixing, the density of vibration, the construction climatic conditions and the curing conditions. Therefore, the cement mortar is stored. .
