High-crack-resistance wear-resistant self-leveling mortar
The invention discloses high-crack-resistance wear-resistant self-leveling mortar, which is prepared from the following raw materials in percentage by weight: 15 to 25 weight percent of crack-resistance Portland cement clinker, 5 to 10 weight percent of auxiliary cementing material, 3 to 7 weight percent of gypsum, 5 to 10 weight percent of heavy calcium powder, 3 to 7 weight percent of modified steel slag powder, 30 to 35 weight percent of 40 to 70-mesh quartz sand and 20 to 25 weight percent of 70 to 120-mesh quartz sand, the auxiliary materials account for the total mass percentage of the raw materials: 0.1-0.8 wt% of redispersible latex powder, 0.2-0.4 wt% of a powdery polycarboxylic acid water reducing agent, 0.01-0.02 wt% of cellulose ether and 0.1 wt% of a defoaming agent. The crack resistance and wear resistance of the self-leveling mortar are improved.
本发明公开了一种高抗裂耐磨自流平砂浆，包括重量百分比的原材料：15～25wt％抗裂硅酸盐水泥熟料、5～10wt％辅助胶凝材料、3～7wt％石膏、5～10wt％重钙粉、3～7wt％改性钢渣粉、30～35wt％40～70目石英砂、20～25wt％70～120目石英砂，以及占原材料总质量百分比的辅料：0.1～0.8wt％可再分散乳胶粉、0.2～0.4wt％粉状聚羧酸减水剂、0.01～0.02wt％纤维素醚、0.1wt％消泡剂。本发明提高了自流平砂浆抗裂性和耐磨性。
