| description | The invention relates to the technical field of building materials, in particular to ultra-high performance concrete and a preparation method thereof. The ultra-high performance concrete is prepared from the following components in parts by weight: 1 part of cement, 0.4-0.7 part of modified micro powder, 0.2-0.5 part of silica fume, 1.2-1.7 parts of quartz sand, 0.27-0.35 part of water, 0.015-0.03 part of water reducing agent powder, 0.006-0.01 part of shrinkage reducing agent, 0.3-1.0% of graphene reinforcing agent and the balance of steel fibers, the total powder mass of the cement, the modified micro powder and the silica fume is 100%, and the total mass of the graphene reinforcing agent is 0.3-1.0%. The mixing amount of the steel fibers is 1-3% by taking the volume of the ultra-high performance concrete as 100%. According to the ultra-high performance concrete, the waste glass powder and the calcium carbonate powder serve as raw materials, the ultra-high performance concrete product with low cost and high |
