Superfine sulfur-containing tailing concrete
The invention discloses superfine sulfur-containing tailing concrete. The superfine sulfur-containing tailing concrete is prepared from the following raw materials: low-clinker cement and superfine sulfur-containing tailings. According to the present invention, the cementing technology principle is adopted, the M32.5 low-clinker composite cement is adopted as the cementing material, and the superfine sulfur-containing tailings are adopted to replace the cement and the water in the same volume so as to prepare the superfine sulfur-containing tailing high-content concrete; sulfate released by acidification of sulfide of the superfine sulfur-containing tailings is fully utilized to excite high-quantity auxiliary materials of the M32.5 cement, the cementing strength is improved, the economic value of the superfine sulfur-containing tailings is improved to the level of the M32.5 cement, waste is turned into wealth, and harm is turned into treasure. The concrete disclosed by the invention is stable in mechanical property and micro-expansive. The method is simple to operate and low in cost, and has a wide application prospect under the background of shortage of raw materials in the building material market.
本发明公开了一种超细含硫尾砂混凝土，包括如下原料：低熟料水泥和超细含硫尾砂。本发明运用胶结技术原理，利用M32.5低熟料复合水泥为胶结料，使用超细含硫尾砂等体积替代水泥与水，实现制备超细含硫尾砂高掺量混凝土。本发明充分利用超细含硫尾砂的硫化物酸化释放的硫酸盐激发M32.5水泥的高量辅料，提高胶结强度，将超细含硫尾砂经济价值提升至M32.5水泥的水平，变废为宝、变害为宝。本发明的混凝土力学性质稳定，微膨胀。本发明操作简单，成本低廉，在建材市场原料紧缺的背景下，具有广阔的应用前景。
