Tungsten tailing high-performance admixture for concrete and preparation method thereof
The invention discloses a high-performance tungsten tailing admixture for concrete and a preparation method of the high-performance tungsten tailing admixture. According to the method, 50-55 parts by weight of tungsten tailings and 1-2 parts by weight of an exciting agent are ground through a turnover ball mill, the Blaine specific surface area of the activated tungsten tailings is controlled to be 450 +/-20 m < 2 >/kg, and the exciting agent is composed of 98.5% of CaO, 1.1% of triethanolamine and 0.4% of ethylene glycol; and then adding 5-10 parts of PII cement, 5-35 parts of fly ash, 5-35 parts of slag powder and 5-10 parts of semi-hydrated gypsum, and blending by using a three-dimensional mixer to fully homogenize all the components to obtain the tungsten tailing composite admixture. The problem of poor workability of the tungsten tailings is solved, and the activity of the tungsten tailings is improved, so that the strength of the concrete is improved, the tungsten tailings and the slag are fully and efficiently utilized, the cost is saved, and the environmental pressure is relieved.
本发明公开了一种混凝土用钨尾矿高性能掺合料及其制备方法。该方法按照重量份计，将50‑55份钨尾矿和1‑2份激发剂用翻转式球磨机进行粉磨，将活化后钨尾矿的勃氏比表面积控制在450±20m2/kg，其中，激发剂由98.5％的CaO、1.1％的三乙醇胺和0.4％的乙二醇组成；然后加入5‑10份PII水泥、5‑35份粉煤灰、5‑35份矿渣粉、5‑10份半水石膏，用三维混料机对其进行共混使所有组分充分均化得到钨尾矿复合掺合料。本发明以解决钨尾矿和易性不好的问题，提高钨尾矿活性，从而提高混凝土的强度，使钨尾矿和矿渣得到充分高效的利用，节约了成本，缓解了环境压力。
