Multi-solid-waste cement coupling admixture and preparation method thereof
The invention relates to a multi-solid-waste cement coupling admixture and a preparation method thereof. The multi-solid-waste cement coupling admixture is prepared from, by weight, 10-20 parts of high-silicon iron tailings, 3-6 parts of slag, 3-6 parts of steel slag, 1-3 parts of water, 1-2 parts of a chemical activating agent, 0.1-0.3 part of a water reducing agent and 0.1-0.2 part of an inhibitor, and has the advantages that a large amount of industrial waste can be consumed, so that environmental pollution can be reduced, waste is turned into wealth, the problems of cost and the like of cement and other raw materials are effectively solved, accumulation of a large amount of tailings can be effectively reduced while cost is saved, the method is an effective way for realizing high-efficiency utilization of resources and keeps ecological balance of water, soil and land, and the problems of single solid waste activation mode, low efficiency, poor activation effect and the like are effectively solved. The admixture produced by the invention can be used for producing various cement products, the comprehensive utilization rate of solid wastes is improved, the environmental pollution is reduced, and the sustainable development of resources is promoted.
本发明涉及一种多固废水泥耦合掺合料及其制备方法，包括以下重量份的原料：高硅铁尾矿10‑20份、矿渣3‑6份、钢渣3‑6份、水1‑3份、化学活化剂1‑2份、减水剂0.1‑0.3份、抑制剂0.1‑0.2份，本发明的优点效果是能够大量消耗工业废弃物，不仅可以减少环境污染，变废为宝；而且有效地解决水泥等原材料成本等问题；另外，可以有效减少大量尾矿堆积，同时节约成本；是实现高效率利用资源的有效途径，保持水土、土地生态平衡；有效地解决固废活化方式单一、效率低、活化效果差等问题。本发明生产的掺合料可用于各类水泥产品的生产，提高了固废的综合利用率，减少了环境污染，促进资源的可持续发展。
