Liquid granulating agent of artificial active mixed material for Portland cement
According to the invention, the liquid granulating agent with specific components and contents is adopted; high-water-content fine tailings or high-water-content construction waste fine slag which are difficult to directly utilize in the prior art, coarse tailings, copper metallurgical slag, industrial gypsum, fly ash, biomass slag, water granulated slag, sandstone squeezing slag, steel slag, casting black slag and ceramic tile slag are mixed into a mixture; different solid wastes with potential pozzolanic activity, such as stone granite powder mud and the like, are prepared into particles which have proper water content, proper strength and proper particle size and are easy to flow; and preparing the granular material into the artificial active mixed material for Portland cement through a grinding activation process. The artificial active mixed material is added into the cement clinker, the obtained Portland cement has the same technical performance as ordinary Portland cement, the technical problem that the micro tailings and the construction waste micro slag are difficult to directly utilize is solved, and huge social, economic and ecological benefits are obtained.
本发明采用特定组分和含量的液体造粒剂，通过造粒工艺，将现有技术难以直接利用的高含水率微细尾矿或含水率较高的建筑垃圾微细渣与粗尾矿、铜冶金渣、工业石膏、粉煤灰、生物质渣、水渣、砂石压榨渣、钢渣、铸造黑渣、瓷砖渣、石材花岗岩粉泥等不同的具有潜在火山灰质活性的固体废弃物制备成具有合适含水率、合适强度、合适粒径且容易流动的粒状物；再通过研磨激发活性工艺，将粒状物制备成硅酸盐水泥用人工活性混合材料；将人工活性混合材料添加到水泥熟料中，得到的硅酸盐水泥具有与普通硅酸盐水泥相同的技术性能，解决了微细尾矿和建筑垃圾微细渣难于直接利用的技术问题，取得巨大的社会经济和生态效益。
