All-solid-waste high-activity composite admixture and preparation method thereof
The invention relates to an all-solid-waste high-activity composite admixture and a preparation method thereof. The all-solid-waste high-activity composite admixture is prepared from the following raw materials: mixed grinding micro powder of steel slag tailings and refining slag, and slag micro powder, wherein in parts by weight, the content of the mixed grinding micro powder is 20 to 30 parts, and the content of the slag micro powder is 70 to 80 parts. Through the synergistic effect of raw material co-doping, the activity of the admixture is improved, and the stability of chemical performance indexes of the admixture is ensured; the use ratio of the admixture in cement and mortar is increased, the consumption of cement is reduced, and the cost is further reduced. According to the invention, resource utilization of metallurgical industry solid wastes such as steel slag tailings, refining slag and blast furnace slag is realized, and the problem that the metallurgical industry solid wastes cannot be consumed due to long-term stockpiling is solved.
本申请涉及一种全固废高活性复合掺合料及其制备方法，所述全固废高活性复合掺合料的原料包括：钢渣尾渣与精炼渣的混磨微粉，以及矿渣微粉；其中，以重量份计，所述混磨微粉的含量为20份～30份，所述矿渣微粉的含量为70份～80份。本申请通过原料复掺的协同作用，提高了掺合料的活性，保证了掺合料理化性能指标的稳定性；提高了掺合料在水泥、砂浆中的使用比例，节约了水泥的消耗，进而降低了成本。本发明实现了钢渣尾渣、精炼渣、高炉矿渣等冶金工业固体废弃物的资源化利用，解决了其长期堆存占地无法消纳的问题。
