Self-leveling mortar and preparation method thereof
The invention discloses self-leveling mortar and a preparation method thereof. The self-leveling mortar provided by the invention comprises the following components in parts by mass: 100-300 parts of a cementing material; 100 parts to 300 parts of fine aggregate; 0 to 6.5 parts of an additive; 0 to 177 parts of water; the cementing material is composed of cement and polishing residues. The preparation method of the self-leveling mortar comprises the following steps: uniformly mixing the cement, the fine aggregate and a part of the additive to prepare a dry material, uniformly mixing the polishing residues, the rest of the additive and a part of the water to prepare a wet material, and uniformly mixing the dry material, the wet material and the rest of the water to obtain the self-leveling mortar. According to the self-leveling mortar disclosed by the invention, a large amount of resin type artificial stone polishing residues are added, so that the lubricity, the water retention capacity and the adhesive property of the self-leveling mortar are improved, the risks of segregation, cracking and hollowing are reduced, and the treatment energy consumption of the polishing residues and the preparation cost of the self-leveling mortar are greatly reduced.
本发明公开了一种自流平砂浆及其制备方法。本发明的自流平砂浆包括以下质量份的组分：胶凝材料：100份～300份；细骨料：100份～300份；外加剂：0份～6.5份；水：0份～177份；所述胶凝材料由水泥和抛光渣组成。本发明的自流平砂浆的制备方法包括以下步骤：将水泥、细骨料和一部分的外加剂混合均匀制成干料，再将抛光渣、剩余的外加剂和一部分的水混合均匀制成湿料，再将干料、湿料和剩余的水混合均匀，即得自流平砂浆。本发明的自流平砂浆中添加有大量的树脂型人造石抛光渣，提高了自流平砂浆的润滑性、保水能力和粘结性能，降低了离析、开裂、空鼓风险，且大幅度降低了抛光渣的处置能耗和自流平砂浆的制备成本。
