Impermeable high-strength concrete and preparation method thereof

The invention relates to impermeable high-strength concrete and a preparation method thereof and relates to the technical field of concrete. The impermeable high-strength concrete comprises: by mass,300-350 parts of cement, 700-750 parts of sand, 1050-1110 parts of broken stones, 80-150 parts of mineral admixtures, 80-120 parts of calcium carbonate, 100-125 parts of steel fibers, 100-150 parts ofpolycarbonate fibers, 5-10 parts of a water reducing agent, 5-8 parts of a tackifier, 3-5 parts of a defoaming agent and 130-180 parts of water. The steel fibers and the polycarbonate fibers are uniformly distributed in the concrete in the stirring process and are intertwined to form a plurality of disorderly distributed fiber skeleton supporting systems, so that the strength of the concrete after solidification is improved. 本发明涉及一种抗渗高强度混凝土及其制备方法，涉及混凝土的技术领域，按照质量份数计，具体包括如下组分：水泥300～350份、砂子700～750份、碎石1050～1110份、矿物掺合料80～150份、碳酸钙80～120份、钢纤维100～125份、聚碳酸酯纤维100～150份、减水剂5～10份、增粘剂5～8份、消泡剂3～5份以及水130～180份。本发明的钢纤维和聚碳酸酯纤维在搅拌过程中均匀分布
