Green low-shrinkage incineration ash-SAP cement-based self-leveling mortar
The invention discloses green low-shrinkage incineration ash-SAP (Super Absorbent Polymer) cement-based self-leveling mortar, which is prepared from the following components in parts by weight: 1.94 to 5.81 parts of incineration ash, 21.30 to 25.18 parts of Portland cement, 10.62 to 13.62 parts of coal ash, 56.10 to 60.10 parts of river sand, 0.008 to 0.016 part of super absorbent resin, 1.50 to 1.60 parts of expanding agent, 0.10 to 0.20 part of water reducing agent, 0.56 to 0.60 part of redispersible latex powder, 0.018 to 0.020 part of cellulose ether, 0.076 to 0.078 part of defoaming agent and 0.76 to 0.78 part of early strength agent. According to the material, part of cement is replaced by the sludge incineration ash, the material has the advantages of low carbon, environmental protection and cost reduction, resource utilization of the incineration ash is achieved, meanwhile, SAP is doped to reduce drying shrinkage, the material has good fluidity, strength and crack resistance, and the method is simple and suitable for industrial production.
本发明公开了一种绿色低收缩焚烧灰‑SAP水泥基自流平砂浆，其组成为：焚烧灰1.94～5.81份，硅酸盐水泥21.30～25.18份，粉煤灰10.62～13.62份，河砂56.10～60.10份，高吸水性树脂0.008～0.016份，膨胀剂1.50～1.60份，减水剂0.10～0.20份，可再分散乳胶粉0.56～0.60份，纤维素醚0.018～0.020份，消泡剂0.076～0.078份，早强剂0.76～0.78份；该材料以污泥焚烧灰替代部分水泥，具有低碳环保、降低成本的优势，实现焚烧灰的资源化利用，同时掺入SAP来减少干燥收缩，使其具有良好的流动度、强度和抗裂性，方法简单，适合工业化生产。
