Ultra-high performance concrete and preparation method thereof
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 performance is prepared, and resource utilization of the glass waste and the calcium carbonate powder is achieved.
本发明涉及建筑材料技术领域，特别涉及一种超高性能混凝土及其制备方法。该超高性能混凝土重量份的组成是：水泥1份，改性微粉0.4～0.7份，硅灰0.2～0.5份，石英砂1.2～1.7份，水0.27～0.35份，减水剂粉剂0.015～0.03份，减缩剂0.006～0.01份，石墨烯增强剂，其中，以水泥、改性微粉和硅灰总粉体质量为100％计，所述石墨烯增强剂的质量掺量为0.3～1.0％，钢纤维，其中，以所述超高性能混凝土的体积计为100％计，所述钢纤维掺量为1～3％。该超高性能混凝土以废弃玻璃粉和碳酸钙粉为原料，制备成本低性能高的超高性能混凝土产品，实现了玻璃废弃物及碳酸钙粉的资源化利用。
