Premixed mortar and preparation method thereof
The invention discloses premixed mortar and a preparation method thereof, and belongs to the technical field of building materials. The premixed mortar is prepared from the following raw materials in parts by weight: 30 to 50 parts of cement, 30 to 40 parts of sea sand with fineness modulus of 1.6 to 2.2, 20 to 30 parts of aluminum slag, 0.03 to 0.08 part of methyl cellulose, 0.1 to 1 part of basalt fiber, 1.5 to 2.0 parts of thickening agent and 0.1 to 0.5 part of polycarboxylate superplasticizer. The thickening agent is prepared from the following raw materials in parts by weight: 50 to 80 parts of bentonite, 10 to 20 parts of Stone ester, 5 to 15 parts of allophane, 5 to 10 parts of fly ash, 0.1 to 0.5 part of triethanolamine oleic soap, 0.1 to 0.5 part of stearic acid and 0.3 to 0.8 part of vinyl acetate. The aluminum slag is used as a raw material to be added into the premixed mortar and then mixed with the thickening agent and other raw materials for use, so that the cost is reduced; the prepared premixed mortar co-treats the aluminum slag, and slag resources can be effectively recycled.
本发明公开了一种预拌砂浆及其制备方法，属于建筑材料技术领域。本发明的预拌砂浆由以下重量份的原料制成：水泥30‑50，细度模数为1.6‑2.2的海砂30‑40，铝渣20‑30，甲基纤维素0.03‑0.08，玄武岩纤维0.1‑1，稠化剂1.5‑2.0，聚羧酸减水剂0.1‑0.5；所述稠化剂由以下重量份的原料制成：膨润土50‑80、石脂10‑20、水铝英石5‑15、粉煤灰5‑10、三乙醇胺油酸皂0.1‑0.5、硬脂酸0.1‑0.5、醋酸乙烯0.3‑0.8。本发明利用铝渣作为原料加入预拌砂浆中，再与稠化剂等原料混合使用，降低成本；制备预拌砂浆协同处置铝渣，可有效回收利用矿渣资源。
