Description

technical field [0001] The invention belongs to the technical field of architectural decoration engineering, and in particular relates to an environment-friendly composite admixture for architectural decoration engineering and a preparation method thereof. [0002] technical background [0003] While the rapid development of my country's iron and steel industry has significantly improved people's material living standards, a large amount of steel slag and slag produced in the production process have also brought great troubles to people's lives. Their stockpiles not only occupy valuable land and pollute the surrounding environment, but are also a huge waste of resources. Steel slag and slag contain a large amount of gelling minerals or glassy substances similar to cement clinker, and have better gelling activity under appropriate conditions after grinding. It has always been the main object of research on the resource utilization of industrial waste slag in cement-based mater...
