Environment-friendly graphene oxide ultra-high performance concrete and preparation method thereof
The invention discloses an environment-friendly graphene oxide concrete with ultra-high performance. The raw materials comprise the following components in parts by mass: 1020.75-1038.00 parts of a cementing material and 80-120 parts of steel fibers; the concrete is characterized by further comprising water, quartz sand, graphene oxide and polycarboxylic acid high-performance water reducing agentpowder, the mass ratio of the water to the cementing material is 0.18, the mass ratio of the quartz sand to the cementing material is 1.1, and the mass of the polycarboxylic acid high-performance water reducing agent powder is 0.3% of the mass of the cementing material. According to the environment-friendly graphene oxide ultra-high-performance concrete, a small amount of graphene oxide with gooddispersity is doped, so that the breaking strength ratio and the toughness of the ultra-high-performance concrete are improved, and the quality problem of the existing ultra-high-performance concreteis solved.
本发明公开了一种环保型氧化石墨烯超高性能混凝土，其原料按质量份比例包括：胶凝材料1020.75－1038.00份、钢纤维80－120份，还包括水、石英砂、氧化石墨烯和聚羧酸高性能减水剂粉剂，所述水与胶凝材料的质量比为0.18，所述石英砂与胶凝材料的质量比为1.1，所述聚羧酸高性能减水剂粉剂质量为胶凝材料质量的0.3％。本环保型氧化石墨烯超高性能混凝土通过掺入具有良好分散性的少量氧化石墨烯，提高了超高性能混凝土的折压强度比和韧性，解决了现有超高性能混凝土的质量问题。
