The invention belongs to the field of building materials, and relates to dry-mixed mortar, in particular to a building dry-mixed mortar composition. The composition comprises the following components in parts by weight: 50-80 parts of aggregate, 10-15 parts of admixture and 3-5 parts of auxiliaries, the aggregate comprises 10-15 wt% of fly ash, 10-15 wt% of iron tailings, 5-8 wt% of zeolite waste residues and glass beads, and the total weight of the aggregate is 100 wt%; the admixture comprises 10 to 20 weight percent of semi-hydrated gypsum, 0.3 to 0.6 weight percent of polypropylene fiber, 1 to 3 weight percent of styrene methyl methacrylate and cellulose ether, and the total weight of the admixture is 100 weight percent; and the auxiliary agent comprises 5-8 wt% of an alkaline activator, 2-4 wt% of a water reducing agent, 0.1-0.2 wt% of an air entraining agent and 0.3-0.5 wt% of a water repellent. By compounding the aggregates, the admixture and the additive, the thixotropic dry-mixed mortar has excellent mechanical properties and good thixotropy, so that the thixotropic dry-mixed mortar is not easy to adhere to an operation tool, and the technical problem that the thixotropy of the dry-mixed mortar becomes poor due to doping of cellulose ether is properly solved.
本申请属于建筑物料的领域，涉及一种干粉砂浆，具体涉及一种建筑干粉砂浆组合物。该组合物，包括如下组分：骨料50～80份、掺料10～15份、助剂3～5份；所述骨料包括粉煤灰10～15wt％、铁尾矿10～15wt％，沸石质废渣5～8wt％、还包括玻化微珠，玻化微珠补足至100wt％；所述掺料包括半水石膏10～20wt％、聚丙烯纤维0.3～0.6wt％、苯乙烯甲基丙烯酸甲酯1～3wt％、还包括纤维素醚，纤维素醚补足至100wt％；所述助剂包括碱性激发剂5～8wt％、减水剂2～4wt％、引气剂0.1～0.2wt％、憎水剂0.3～0.5wt％。本申请通过复配各骨料、掺料和添加剂，在具有优异的力学性能的同时，还具有良好的触变性，使之不易粘附在操作工具上，妥善地优化了因为掺杂纤维素醚而引起的干粉砂浆触变性变差的技术问题。
