Ultra-high-performance concrete prepared from sludge powder of waterworks
The invention relates to the technical field of building materials, and particularly discloses ultra-high-performance concrete prepared from sludge powder of waterworks. The ultra-high-performance concrete comprises the following components in parts by weight: 650-850 parts of cement, 200-400 parts of a composite mineral admixture, 1010-1020 parts of standard sand, 150-180 parts of steel fibers, 18-25 parts of a water reducing agent and 140-190 parts of water. The cement and the composite mineral admixture form a cementing material, the cementing material is not less than 1010 parts, and a water-binder ratio is 0.14 to 0.16. The concrete of the invention has the characteristics of easy availability of raw materials, environment friendliness, low cement consumption, low manufacturing cost and perfect component composition.
本发明涉及建筑材料技术领域，具体公开了一种采用自来水厂污泥粉制备的超高性能混凝土，按重量份计，包括以下组分，水泥650～850份，复合矿物掺合料200～400份，标准砂1010～1020份，钢纤维150～180份，减水剂18～25份，水140～190份；水泥和复合矿物掺合料组成胶凝材料，胶凝材料不低于1010份；所述水胶比为0.14～0.16。本发明具有原料易得、对环境较为友好、水泥用量较少、制造成本较低和组分组成较为完善的特点。
