High-impermeability graphene oxide concrete and preparation method thereof
The invention relates to the technical field of concrete engineering materials, in particular to high-permeability-resistance graphene oxide concrete and a preparation method thereof.The high-permeability-resistance graphene oxide concrete is prepared from 200 kg/m < 3 > to 280 kg/m < 3 > of cement, 150 kg/m < 3 > to 230 kg/m < 3 > of superfine admixture, 780 kg/m < 3 > to 860 kg/m < 3 > of tailing sand, 1010 kg/m < 3 > to 1090 kg/m < 3 > of graded broken stone, 4.5 kg/m < 3 > to 9 kg/m < 3 > of efficient water reducing agent, 0.2 kg/m < 3 > to 0.6 kg/m < 3 > of slump retaining agent, 8 kg/m < 3 > to 12 kg/m < 3 > of permeability-resistance component and 0.2 kg/m < 3 > to 0.4 kg/m < 3 > The graphene oxide solution with good dispersion is adopted as a raw material to be added into the concrete, crystal nucleuses necessary for crystallization can be provided for cement hydration products, hydration product crystals are refined, and hydration reaction is promoted to be stably carried out for a long time, so that the hydration degree is improved, the internal porosity of the concrete is reduced, the pore structure is optimized, and the system is more compact and uniform; therefore, the strength of the concrete is greatly improved, and the impermeability is improved.
本发明涉及混凝土工程材料的技术领域，具体涉及一种高抗渗氧化石墨烯混凝土及其制备方法，按照单方用量计，原料的用量为：水泥200～280kg/m3、超细掺合料150～230kg/m3、尾矿砂780～860kg/m3、级配碎石1010～1090kg/m3、高效减水剂4.5～9kg/m3、保坍剂0.2～0.6kg/m3、抗渗组分8～12kg/m3、氧化石墨烯溶液0.2～0.4kg/m3，水灰比控制范围0.35～0.40。本发明采用分散良好的氧化石墨烯溶液作为原料加入混凝土中，可为水泥水化产物提供结晶所必需的晶核，使水化产物晶体细化，促进水化反应长期稳定进行，从而提高水化度，减少混凝土内部孔隙率，优化孔结构，使体系更加致密均匀，从而大幅提高混凝土的强度，并改善抗渗性能。
