以微沫剂(或其他引气剂)加水搅拌成含有细小分散的气泡的水溶液,然后加入水泥和砂(或者水泥、石灰和砂)中,搅拌均匀,得到的多孔砂浆,被称为微沫剂砂浆。这种砂浆的性质可以通过掺入微沫剂来控制,也可以将微沫剂的水溶液与水泥、砂一起强烈搅拌而制得。它具有和易性好、操作方便、施工效率和质量高等优点。还可以通过减少用水量,使水泥颗粒分散,从而使砂浆获得较高的强度。砂浆硬化后含有大量的细小、
The micro-foam (or other air-entraining agent) is added with water and stirred to form an aqueous solution containing fine dispersed bubbles, and then added to the cement and sand (or cement, lime, and sand) and stirred uniformly to obtain the porous mortar, which is called micro-foam Agent mortar. The nature of the mortar can be controlled by the incorporation of a micro-foam agent, and can also be obtained by vigorously stirring the aqueous solution of the micro-foam agent with cement and sand. It has the advantages of easy workability, convenient operation, construction efficiency and high quality. It is also possible to make the mortar obtain higher strength by reducing the amount of water and dispersing the cement particles. After the mortar has hardened, it contains a lot of small,
