Preparation method of concrete based on composite modification of graphene oxide and metakaolin
The invention relates to the field of novel materials for civil engineering, and discloses a preparation method of concrete based on composite modification of graphene oxide and metakaolin, micro pores and cracks in the concrete are filled through doping of GO and MK, and the pore structure is refined, so that the impermeability of the concrete is greatly improved, and meanwhile, the water absorption rate of the concrete is reduced. GO and MK have a synergistic effect, so that the limitation of a single modified material is overcome, the filling effect improves the grain composition between gelling systems and the cement particle distribution of an interface region, optimizes the pore size distribution, and improves the compactness of the cement-based material.
本发明涉及土木工程新型材料领域，且公开了基于氧化石墨烯和偏高岭土复合改性的混凝土制备方法，GO与MK的掺入填充了混凝土中的微小孔隙和裂缝，细化了孔隙结构，从而使混凝土的抗渗性能大大提升，同时降低了混凝土的吸水率。GO与MK协同增效，克服了单一改性材料的局限性，填充效应改善了胶凝体系间的颗粒级配、界面区域的水泥颗粒分布，优化孔隙尺寸分布，改善了水泥基材料的密实度。
