Concrete pumping agent and preparation process thereof
The invention discloses a concrete pumping agent which is prepared by mixing the following raw materials in percentage by mass: 93% of tailings, 7% of slag and 5% of a grinding aid. According to the invention, part of cement in commercial concrete can be effectively replaced, so that the cement consumption in the commercial concrete is effectively reduced; and the use amount of cement in constructional engineering every year can be reduced, so that the effects of energy conservation and emission reduction are achieved. According to the invention, the suitability of commercial concrete can be effectively improved, and the pumping performance of the concrete can be fundamentally improved. The tailings of the iron ore and the high-calcium stone are both waste utilization, and resources can be saved to the maximum extent.
本发明公开了一种混凝土泵送剂，由下述质量比例配比的原料混合制成：尾矿石93%，炉渣7%，助磨剂5%。本发明可有效替代商品混凝土中部分水泥的使用，从而有效降低商品混凝土中的水泥用量；可减少每年在建筑工程中的水泥用量，从而达到节能减排的作用。本发明能有效提高商品混凝土的合宜性，使混凝土的泵送性能得到根本性的改善。本发明中的铁矿及高钙石的尾矿，均为废物利用，可最大限度的节约资源。
