The invention relates to the technical field of concrete preparation, and particularly discloses high-strength impervious composite concrete and a preparation method thereof. The high-strength impervious composite concrete is prepared from the following raw materials: cement, superfine fly ash, slag powder, sand, gravel, an additive, modified fibrilia and water, the modified fibrilia is obtained by coating the surface of fibrilia with a graphene-based film. A protective layer is formed on the surface of the jute fiber through the graphene-based film, so that the corrosion degradation process of the jute fiber in a concrete system is slowed down, long-term and effective mechanical strength and elasticity of the jute fiber are kept, the probability that the concrete structure cracks is reduced, and the durability of the impermeability of the concrete is effectively improved.
本申请涉及混凝土制备技术的领域，具体公开了一种高强度抗渗复合混凝土及其制备方法。一种高强度抗渗复合混凝土其原料包括水泥、超细粉煤灰、矿渣粉、砂子、碎石、外加剂、改性麻纤维和水；改性麻纤维由在麻纤维表面包覆石墨烯基膜得到。本申请通过石墨烯基膜在麻纤维表面形成保护层，从而减缓麻纤维在混凝土体系中的腐蚀降解过程，因此有利于麻纤维保持长久有效的机械强度和弹力，从而降低混凝土结构产生裂缝的概率，进而有效提高了混凝土抗渗性能的耐久性。
