为了改善建筑砂浆的和易性,通常在水泥砂浆中加入石灰膏,但石灰膏在运输和使用中容易撒漏,污染环境,存放不便。近几年开始使用的石灰粉虽然稍能改变环境污染问题,但由于造价高,难以推广。掺用砂浆微沫剂,能使水泥砂浆具有与混合砂浆相近的和易性,但使用前要先用水预溶解,而且掺量不易控制,一旦超量,将使砂浆强度显著降低。MC砂浆外加剂以粉末状形式加入,采用计量小包装,一袋水泥掺 In order to improve the workability of the building mortar, lime plaster is usually added to the cement mortar. However, the lime paste is easily spilled during transportation and use, polluting the environment and being inconvenient to store. Although lime powder that has been used in recent years can slightly change environmental pollution, it is difficult to promote due to its high cost. The use of mortar micro-foam agent can make the cement mortar have similar workability with the mixed mortar, but it must be pre-dissolved with water before use, and the amount of the mortar is not easy to control. Once the amount is exceeded, the strength of the mortar will be significantly reduced. The MC mortar admixture is added in the form of a powder, using a small measuring package, a bag of cement
