本文介绍以砂、普通硅酸盐水泥、生石灰粉和粉煤灰作为主要原料,加入无水氯化钙和甲基纤维素外加剂,研制蒸压加气混凝土砌块专用干粉砂浆。通过试验对比,无水氯化钙的保水性能优于甲基纤维素;在试验的三个水平下,生石灰粉对砂浆粘结性的负面影响较大,不掺生石灰粉时,砂浆的粘结性能良好。 This paper introduces the sand, ordinary portland cement, quicklime and fly ash as the main raw material, adding anhydrous calcium chloride and methyl cellulose admixture, the development of autoclaved aerated concrete block dedicated dry mortar. Through the experimental comparison, the water retention capacity of anhydrous calcium chloride is better than that of methylcellulose. Under the three levels of test, the negative effect of quick lime powder on the mortar cohesiveness is great. When the lime powder is not mixed, Good performance.
