Adhesive mortar capable of being used for autoclaved aerated concrete blocks and preparation method of adhesive mortar
The invention discloses adhesive mortar capable of being used for autoclaved aerated concrete blocks, which is prepared from the following components in parts by weight: 20 to 30 parts of cement, 40 to 50 parts of sand, 20 to 25 parts of organosilane modified fly ash, 0.8 to 1 part of polyvinylpyrrolidone, 1 to 1.2 parts of redispersible latex powder, 0.2 to 0.5 part of polypropylene fiber, 0.3 to 0.5 part of hydroxypropyl methyl cellulose, 0.1 to 0.3 part of retarder and 16 to 22 parts of water. The invention also discloses a preparation method of the adhesive mortar, and the adhesive mortar prepared by the invention not only has excellent mechanical properties and is firmly bonded with a substrate, but also can effectively improve the occurrence of hollowing or cracking phenomenon of a plaster layer of a wall when being used for bonding autoclaved aerated concrete blocks.
本发明公开了一种可用于蒸压加气混凝土砌块的粘结砂浆，以重量份计，包括以下组分：水泥20‑30份，砂40‑50份，有机硅烷改性粉煤灰20‑25份，聚乙烯吡咯烷酮0.8‑1份，可再分散乳胶粉1‑1.2份，聚丙烯纤维0.2‑0.5份，羟丙基甲基纤维素0.3‑0.5份，缓凝剂0.1‑0.3份，水16‑22份。本发明还公开了该粘结砂浆的制备方法，本发明制得的粘结砂浆不仅力学性能优异，与基底粘结牢固，用于蒸压加气混凝土砌块粘结时可有效改善墙体抹灰层空鼓或开裂现象的发生。
