Full-doping-amount graphite tailing ultra-high performance concrete and preparation method thereof
The invention belongs to the field of ultra-high performance concrete, and particularly relates to full-doping-amount graphite tailing ultra-high performance concrete and a preparation method thereof, in particular to full-doping-amount graphite tailing ultra-high performance concrete and a preparation method of the full-doping-amount graphite tailing ultra-high performance concrete. The invention aims to solve the problem that graphite tailings cannot be efficiently used due to low usage amount of the graphite tailings when the graphite tailings are used for preparing concrete in the current cement-based composite material field. The graphite tailings are doped into the components of the ultra-high performance concrete in the form of all aggregates, a cement-superfine fly ash microbead-silica fume ternary gelling system is adopted to optimize the compactness of a concrete matrix, the use amount of mixing water is regulated and controlled, and a defoaming agent-water reducing agent binary admixture system is matched to improve the working performance of the fully-doped graphite tailings UHPC. The proportioning system disclosed by the invention not only has relatively high compressive strength, but also has excellent construction performance, and is beneficial to promoting the application of ultra-high performance concrete and relieving ecological problems caused by massive accumulation of graphite tailings to a relatively great extent.
一种全掺量石墨尾矿超高性能混凝土及其制备方法，本发明属于超高性能混凝土领域，具体涉及一种全掺量石墨尾矿超高性能混凝土及其制备方法。本发明要解决当前水泥基复合材料领域采用石墨尾矿进行混凝土制备时，石墨尾矿用量较低无法高效使用石墨尾矿的问题。本发明将石墨尾矿以全部骨料的形式掺入超高性能混凝土的组分内，采用水泥‑超细粉煤灰微珠‑硅灰三元胶凝体系优化混凝土基体密实度，调控拌合水用量和搭配消泡剂‑减水剂二元外加剂体系以提高全掺量石墨尾矿UHPC的工作性能。本发明的配比体系不但拥有较高的抗压强度，还兼备优异的施工性能，有助于推动超高性能混凝土的应用以及较大程度缓解石墨尾矿大量堆积所造成的生态问题。
