Steel slag modifier and application thereof
The invention relates to the technical field of metallurgical solid waste resource utilization, and provides a steel slag modifier and application thereof.The steel slag modifier comprises, by weight, 32-50 parts of active kaolin, 15-23 parts of coal gangue, 7-10 parts of red mud and 1-5 parts of kieselguhr, the steel slag modifier is used for modifying steel slag, and the mass ratio of the steel slag modifier to the steel slag is (3-4): 20. Through the technical scheme, the problems of high content of free calcium oxide in the steel slag and poor volume stability of the steel slag in the prior art are solved.
本发明涉及冶金固废资源化利用技术领域，提出了一种钢渣改质剂及其应用，其中，钢渣改质剂包括以下重量份的组分：活性高岭土32‑50份，煤矸石15‑23份，赤泥7‑10份，硅藻土1‑5份，钢渣改质剂用于钢渣改质，钢渣改质剂与钢渣的质量比为3‑4：20。通过上述技术方案，解决了现有技术钢渣中游离氧化钙含量高、钢渣体积安定性差的问题。
