High-strength wet-mixed mortar and preparation method thereof
The invention relates to the technical field of wet-mixed mortar, and provides high-strength wet-mixed mortar and a preparation method thereof, the high-strength wet-mixed mortar comprises the following components by weight: 550-600 parts of quartz sand, 80-100 parts of cement, 30-40 parts of fly ash, 25-35 parts of mineral powder, 6-9 parts of reinforced fiber, 5-8 parts of a water reducer, 0.5-1.5 parts of a retarder, 1-3 parts of an antifoaming agent, and 90-100 parts of water; the reinforced fibers are composed of polypropylene fibers, polyvinyl alcohol fibers and polyacrylonitrile fibers; the mass ratio of the polypropylene fiber to the polyvinyl alcohol fiber to the polyacrylonitrile fiber is 2: 1: (1-2). According to the technical scheme, the problems of low splitting tensile strength and compressive strength of the wet-mixed mortar in the prior art are solved.
本发明涉及湿拌砂浆技术领域，提出了一种高强度湿拌砂浆及其制备方法，包括以下重量份组分：550‑600份石英砂、80‑100份水泥、30‑40份粉煤灰、25‑35份矿粉、6‑9份增强纤维、5‑8份减水剂、0.5‑1.5份缓凝剂、1‑3份消泡剂、90‑100份水；所述增强纤维由聚丙烯纤维、聚乙烯醇纤维和聚丙烯腈纤维组成；所述聚丙烯纤维、聚乙烯醇纤维和聚丙烯腈纤维的质量比为2:1:1‑2。通过上述技术方案，解决了现有技术中湿拌砂浆的劈裂抗拉强度和抗压强度低的问题。
