Ultra-high performance concrete prepared from gold mine tailings, and preparation method and application thereof
The invention provides ultra-high performance concrete prepared from gold mine tailings as well as a preparation method and application thereof, and relates to the field of recycling of gold mine tailings. The ultra-high performance concrete prepared from the gold mine tailings is prepared from the following components in parts by weight: 35-40 parts of cement, 4-6 parts of silica fume, 2-3 parts of fly ash, 5-6 parts of gold mine tailing powder, 12-15 parts of gold mine tailing sand, 27-34 parts of quartz sand, 6-7 parts of water, 5-7 parts of steel fibers, a polycarboxylate superplasticizer and a defoaming agent. According to the ultra-high-performance concrete prepared from the gold mine tailings, the gold mine tailings with different granularities are combined with other raw materials of the concrete to prepare the ultra-high-performance concrete and the concrete member thereof, so that the gold mine tailings can be effectively recycled, and the problem that the existing gold mine tailings are large in stock, low in cost and the like can be solved by turning waste into wealth. And the problems of environmental pollution, serious dust raising, difficulty in management and the like caused by incapability of effective treatment are solved.
本发明提供一种用金矿尾矿制成的超高性能混凝土、制备方法及应用，涉及金矿尾矿砂回用领域。所述用金矿尾矿制成的超高性能混凝土，按重量份计，由如下组分组成：水泥35‑40份，硅灰4‑6份，粉煤灰2‑3份，金矿尾矿粉5‑6份，金矿尾矿砂12‑15份，石英砂27‑34份，水6‑7份，钢纤维5‑7份，聚羧酸减水剂和消泡剂。本发明的用金矿尾矿制成的超高性能混凝土，通过利用不同粒度的金矿尾矿与混凝土其他原料结合，制成超高性能混凝土及其混凝土构件，能够对金矿尾矿进行有效回用，变废为宝能够解决由于现有金矿尾矿存量大，无法获得有效处理而导致的环境污染、扬尘严重、管理困难等问题。
