High-flexural-strength wear-resistant hybrid fiber concrete and preparation method thereof
The invention relates to high-flexural-strength wear-resistant hybrid fiber concrete and a preparation method thereof. The hybrid fiber concrete comprises the following raw materials in parts by weight: 300-400 parts of cement, 0-100 parts of fly ash, 600-850 parts of sand, 1000-1400 parts of gravels, 100-200 parts of water, 30-150 parts of modified steel fibers, 2-10 parts of polyvinyl alcohol fibers and 3-20 parts of additives. According to the prepared hybrid fiber concrete, by improving the dispersity and cohesiveness of the fibers in the concrete and controlling the mutual doping proportion and doping amount of the steel fibers and the polyvinyl alcohol fibers, the fracture resistance and wear resistance of the concrete are remarkably improved. The prepared concrete is good in workability, simple in preparation process and beneficial to large-scale construction, and can be widely applied to concrete structures in the fields of civil engineering, municipal administration, traffic and the like.
本发明涉及一种高抗折耐磨混杂纤维混凝土及其制备方法，其原料重量份数分别为：水泥300～400份、粉煤灰0～100份，砂600～850份、碎石1000～1400份、水100～200份、改性钢纤维30～150份、聚乙烯醇纤维2～10份，外加剂3～20份。本发明制备的混杂纤维混凝土通过改善纤维在混凝土中的分散和粘聚性，控制钢纤维和聚乙烯醇纤维互掺比例和掺量，显著提高了混凝土的抗折耐磨性能。且本发明制备的混凝土工作性好，制备工艺简单，利于大规模施工，可以广泛应用于土木、市政、交通等领域的混凝土结构。
