Graphene oxide ultra-high performance concrete with low cement consumption and preparation method thereof
The invention provides graphene oxide ultra-high performance concrete with low cement consumption, which belongs to the technical field of building materials. The concrete comprises the following components in parts by weight: 100 parts of cement, 30-50 parts of silica fume, 60-120 parts of fly ash, 10-50 parts of slag powder, 80-120 parts of quartz sand, 30-50 parts of water, 20-50 parts of steelfiber, 2-10 parts of a water reducing agent and 1-10 parts of graphene oxide. The invention also provides a preparation method of the ultra-high performance concrete. The graphene oxide is compoundedwith the steel fiber concrete doped with the mineral fine powder, and the graphene oxide can promote cement hydration, improve the early and later strength of the concrete, improve the interface conditions of a matrix and steel fibers and improve the binding strength of the matrix and the steel fibers, so that the breaking strength of the concrete is improved. The graphene oxide can improve the pore structure of the concrete, so that the concrete is denser, the strength of the concrete is improved, concrete strength shrinkage caused by steam curing is avoided, and the durability of the concrete is further improved.
本发明提供一种氧化石墨烯低水泥用量超高性能混凝土，属于建筑材料技术领域。按重量份数计，包括水泥100份，硅灰30～50份，粉煤灰60～120份，矿渣粉10～50份，石英砂80～120份，水30～50份，钢纤维20～50份，减水剂2～10份，氧化石墨烯1～10份。本发明还提供超高性能混凝土的制备方法。氧化石墨烯与掺有矿物细粉的钢纤维混凝土复合，氧化石墨烯会促进水泥水化，提高混凝土的早期和后期强度，改善基体与钢纤维的界面条件，提高其绑结强度,进而提高混凝土的抗折强度。氧化石墨烯可以改善混凝土的孔隙结构，使混凝土更密实，提高混凝土的强度，避免蒸汽养护后引起的凝土强度倒缩，进而提高混凝土的耐久性。
