Pumping castable and preparation method thereof
The invention belongs to the field of buildings, and particularly relates to a pumping castable and a preparation method thereof. The pumping castable comprises the following components by mass: 60-65 parts of high-alumina aggregate, 15-25 parts of high-alumina fine powder, 3-5 parts of silica powder, 3-5 parts of alumina micro powder, 5-10 parts of a high-alumina cement binder, 0.06-0.1 part of sodium tripolyphosphate, 0.06-0.1 part of an FDN water reducer, 0.1-0.3 part of explosion-proof fiber, and 0.3-0.5 part of hydroxymethyl cellulose. The invention solves the problem that an existing castable is insufficient in flowability; the flowability and viscosity of the material are improved by improving grain size matching of the material and increasing the proportion of superfine powder; and meanwhile, by adding hydroxymethyl cellulose, the curing speed of the material is decreased, and pipe blocking caused by material curing in the pumping process is prevented.
本发明属于建筑领域，具体涉及一种泵送浇注料及其制备方法，其质量配比如下：高铝骨料60‑65份、高铝细粉15‑25份、硅微粉3‑5份、氧化铝微粉3‑5份、高铝水泥结合剂5‑10份、三聚磷酸钠0.06‑0.1份、FDN减水剂0.06‑0.1份、防爆纤维0.1‑0.3份、羟甲基纤维素0.3‑0.5份。本发明解决现有浇注料流动性不够的问题，通过改善物料的颗粒级配合，增加超微粉比例，从而增加材料的流动性和粘稠度，同时通过添加羟甲基纤维素，使材料的固化速度变慢，防止在泵送过程中材料固化堵管。
