The invention discloses a high-strength corrosion-resistant concrete material and a preparation method thereof. The preparation method comprises the steps: firstly, weighing all component raw materials, evenly mixing, ball-milling and screening to obtain admixture powder; melting and drawing basalt, rubber particles, epoxy resin and other substances to prepare modified fibers; utilizing hydrofluoric acid to enable the vitrified microspheres to be porous, loading graphene oxide sheets on the porous microspheres through polymerization reaction, adhering the porous microspheres and the modified fibers through the graphene oxide sheets, and mixing and stirring with cement, sandstone and an admixture to obtain the high-strength corrosion-resistant concrete mortar. The invention provides the high-strength corrosion-resistant concrete and the preparation method thereof. In the preparation process, the ratio and the reaction time are reasonably controlled, and the corrosion resistance, the high-temperature stability and the mechanical property of the prepared concrete sample are effectively improved; meanwhile, due to addition of industrial waste such as the waste ceramic tile powder and the waste rubber particles, the water consumption is reduced, environmental friendliness is achieved, the construction cost is greatly reduced, and high practicability is achieved.
本发明公开了一种高强度耐腐蚀的混凝土材料及其制备方法，首先称取各组分原料，混合均匀并球磨过筛得到掺和料粉体；将玄武岩、橡胶颗粒、环氧树脂等物质熔融拉丝，制成改性纤维；利用氢氟酸使玻化微球多孔，通过聚合反应将氧化石墨烯片负载在多孔微球上，多孔微球和改性纤维通过氧化石墨烯片粘合，与水泥、砂石和掺和料混合搅拌得到高强度耐腐蚀混凝土砂浆；本发明中提供了一种高强度耐腐蚀的混凝土及其制备方法，制备过程中合理控制配比和反应时间，制备得到的混凝土样品耐腐蚀性、高温稳定性、力学性能均得到有效改善，同时废瓷砖粉、废橡胶颗粒等工业废料的加入降低了用水量，绿色环保，大大节约了建造成本，具有较高的实用性。
