Ultrahigh-toughness wear-resistant concrete and preparation method thereof
The invention relates to ultrahigh-toughness wear-resistant concrete and a preparation method thereof. The concrete is prepared from the following raw materials in parts by weight: 100 parts of cement, 25 to 30 parts of fly ash, 30 to 35 parts of steel slag, 120 to 200 parts of coarse aggregate, 200 to 240 parts of fine aggregate, 5 to 10 parts of silica fume, 1.0 to 1.5 parts of a water reducing agent, 20 to 30 parts of water and carbon fibers, the carbon fibers are polypyrrole-coated carbon fibers, and the use amount of the polypyrrole-coated carbon fibers is 0.8-1.5% of the total volume of the concrete. The polypyrrole-coated carbon fiber is added into the preparation raw materials of the concrete, and the polypyrrole layer is coated on the surface of the carbon fiber, so that the roughness of the surface of the carbon fiber is increased, mixing and infiltration of the carbon fiber and other inorganic materials in the concrete are facilitated, and the dispersity of the carbon fiber in the concrete is further improved; the concrete has ultrahigh toughness on the premise of high wear resistance, and has a good application prospect.
本申请涉及一种超高韧性耐磨混凝土及其制备方法。以重量份数计，混凝土的制备原料包括如下组分：水泥100份，粉煤灰25~30份，钢渣30~35份，粗骨料120~200份，细骨料200~240份，硅灰5~10份，减水剂1.0~1.5份，水20~30份，碳纤维；所述碳纤维为聚吡咯包裹的碳纤维，聚吡咯包裹的碳纤维的用量为混凝土总体积的0.8~1.5%。该混凝土的制备原料中添加了聚吡咯包裹的碳纤维，其在碳纤维的表面包裹一层聚吡咯层，增加了碳纤维表面的粗糙度，更利于碳纤维与混凝土中其他无机材料的混合与浸润，进而提高了碳纤维在混凝土中分散性，使混凝土在具有高耐磨性的前提下还具有超高的韧性，应用前景良好。
