Repair mortar for ALC (autoclaved lightweight concrete) plate and preparation method of repair mortar
The invention discloses repair mortar for an ALC plate. The repair mortar is prepared from the following raw materials in parts by weight: 80 to 120 parts of white cement, 120 to 180 parts of dried sand, 20 to 35 parts of heavy calcium powder, 0.2 to 0.8 part of cellulose, 0.1 to 0.5 part of starch ether and 0.1 to 0.5 part of latex powder. Specifically, the mortar comprises the following raw materials in parts by weight: 90-120 parts of white cement, 140-160 parts of dried sand, 26-32 parts of heavy calcium powder, 0.4-0.6 part of cellulose, 0.1-0.5 part of starch ether and 0.1-0.5 part of latex powder. The white cement is white Portland cement with the strength grade of 42.5 or 52.5; the moisture content of the dried sand is less than or equal to 5%, and the particle size of the dried sand is 50-120 meshes. The repair mortar has excellent compressive strength, cohesiveness, crack resistance and freezing resistance, and provides powerful guarantee for repair of the ALC plate.
本发明公开了一种ALC板材用修补砂浆，包括如下重量份的原料：白水泥80‑120份、烘干砂120‑180份、重钙粉20‑35份、纤维素0.2‑0.8份、淀粉醚0.1‑0.5份、乳胶粉0.1‑0.5份；具体地，包括如下重量份的原料：白水泥90‑120份、烘干砂140‑160份、重钙粉26‑32份、纤维素0.4‑0.6份、淀粉醚0.1‑0.5份、乳胶粉0.1‑0.5份；所述白水泥为强度等级为42.5或52.5的白色硅酸盐水泥；所述烘干砂的含水率≤5％，所述烘干砂的粒径为50‑120目。该修补砂浆具有优异的抗压强度，粘结性，抗裂性能和抗冻性，为ALC板的修复提供了有力的保障。
