Anti-freezing cement-based grouting material prepared based on iron tailing sand and preparation method of anti-freezing cement-based grouting material
The invention relates to an anti-freezing cement-based grouting material prepared based on iron tailing sand and a preparation method of the anti-freezing cement-based grouting material. The anti-freezing cement-based grouting material is prepared from the following components in parts by weight: 900-1000 parts of ordinary Portland cement, 990-1100 parts of iron tailing sand, 40-50 parts of aluminate cement, 4-8 parts of a high-performance water reducing agent, 0.2-0.6 part of a plastic expanding agent, 1.2-1.6 parts of a thickening plastic retaining agent and 4-8 parts of an anti-freezing early strength agent. The method comprises the following steps: mixing aluminate cement, a high-performance water reducing agent, an anti-freezing early strength agent, a plastic expanding agent and a thickening plastic retaining agent to prepare a composite additive; and then putting the iron tailing sand and the ordinary Portland cement into a rotating stirrer for stirring, and in the stirring process, putting the composite additive into the stirrer for stirring for 3-5 minutes to obtain the iron tailing sand anti-freezing cement-based grouting material. The iron tailing sand is adopted to replace quartz sand to serve as aggregate to prepare the grouting material, the preparation cost can be reduced, the iron tailing sand can be consumed, waste is turned into wealth, and the influence of the iron tailing sand on the ecological environment is reduced.
本发明涉及一种基于铁尾矿砂制备的防冻型水泥基灌浆材料及其制备方法，包括以下重量份的组分制备而成：普通硅酸盐水泥：900～1000份，铁尾矿砂：990～1100份，铝酸盐水泥：40～50份，高性能减水剂：4～8份，塑性膨胀剂：0.2～0.6份，增稠保塑剂：1.2～1.6份，防冻早强剂：4～8份。方法如下：将铝酸盐水泥、高性能减水剂、防冻早强剂、塑性膨胀剂以及增稠保塑剂混合制成复合外加剂；然后将铁尾矿砂和普通硅酸盐水泥放入转动的搅拌机中进行搅拌，搅拌的过程中，将上述复合外加剂放入搅拌机中，搅拌3～5分钟，得到铁尾矿砂防冻型水泥基灌浆料。采用铁尾矿砂代替石英砂作为骨料制备灌浆材料，可以降低制备成本，并可以消耗铁尾矿砂，变废为宝，减少铁尾矿砂对生态环境的影响。
