The invention relates to the technical field of building materials, and provides compression-resistant dry-mixed mortar and a preparation method thereof.The compression-resistant dry-mixed mortar is prepared from, by mass, 40-50 parts of cement, 25-35 parts of sand, 10-15 parts of glass powder, 1-5 parts of stone powder, 1-2 parts of redispersible latex powder, 1-3 parts of modified polypropylene fiber, 0.5-1.5 parts of thickening agent, 5-10 parts of expanding agent and 1-2 parts of water reducing agent; the modified polypropylene fibers are polypropylene fibers which are firstly modified by an amino silane coupling agent and then modified by 2, 5-disulfobenzaldehyde. Through the technical scheme, the problem of low compressive strength of the dry-mixed mortar in the prior art is solved.
本发明涉及建筑材料技术领域，提出了一种抗压干混砂浆及其制备方法，一种抗压干混砂浆，包括以下质量份的组分：水泥40~50份、砂25~35份、玻璃粉10~15份、石粉1~5份、可再分散乳胶粉1~2份、改性聚丙烯纤维1~3份、增稠剂0.5~1.5份、膨胀剂5~10份、减水剂1~2份；所述改性聚丙烯纤维为先经氨基硅烷偶联剂改性再经2,5‑二磺基苯甲醛改性的聚丙烯纤维。通过上述技术方案，解决了现有技术中的干混砂浆抗压强度低的问题。
