Anti-impact wear-resistant concrete for hydraulic engineering and preparation method thereof
The invention provides impact-resistant and wear-resistant concrete for hydraulic engineering and a preparation method of the impact-resistant and wear-resistant concrete. The impact-resistant and wear-resistant concrete comprises the following components: ordinary Portland cement, silica fume, HF fly ash, slag, steel fibers, epoxy resin, polypropylene fibers, chopped igneous rock fibers, iron carbonate and a water reducing agent. The preparation method comprises the following steps: preparing the raw materials according to a set ratio; the preparation method comprises the following steps: adding ordinary Portland cement, silica fume, slag, steel fibers and chopped igneous rock fibers into a double-cone mixer, and uniformly mixing to obtain a mixture A; adding epoxy resin and polypropylene fiber into a stirrer, and uniformly stirring to obtain a mixture B; adding the mixture B, HF fly ash, a water reducing agent and iron carbonate into the mixture A, and uniformly stirring to obtain the impact-resistant and wear-resistant concrete. The wear resistance, strength and corrosion resistance of the concrete can be improved.
本发明提供了一种水利工程用抗冲耐磨混凝土及其制备方法，所述抗冲耐磨混凝土包括以下组分：普通硅酸盐水泥、硅灰、HF粉煤灰、矿渣、钢纤维、环氧树脂、聚丙烯纤维、短切火成岩纤维、碳酸铁和减水剂；制备方法包括以下步骤：按设定配比准备好原材料；将普通硅酸盐水泥、硅灰、矿渣、钢纤维、短切火成岩纤维加入双锥混料机中混合均匀，得到混合物A；将环氧树脂和聚丙烯纤维加入到搅拌机中搅拌均匀，得到混合物B；将所述混合物B、HF粉煤灰、减水剂和碳酸铁投入所述混合物A中，搅拌均匀，得到抗冲耐磨混凝土；本发明能提高混凝土耐磨性、强度以及耐腐蚀性。
