More Information
Summary:The invention belongs to the technical field of ecological environment, and discloses a steel slag desulfurization by-product solidified sludge-based unfired ceramsite and a preparation method thereof. The unfired ceramsite is prepared from the following raw materials in parts by mass: 35-70 parts of sludge, 5-30 parts of a steel slag desulfurization byproduct, 10-20 parts of cement, 5-25 parts of a mineral admixture, 1-2 parts of an exciting agent and 0.1-1 part of a dispersing agent. According to the invention, the steel slag desulfurization by-product is mainly used as the curing agent and cooperates with the cement and the mineral admixture, and the exciting agent, the dispersing agent and the like are supplemented to enhance the curing effect on the building sludge. Moreover, large-scale production and engineering application of the steel slag desulfurization byproducts and the sludge can be realized, the problem that a large number of steel slag desulfurization byproducts and sludge are stacked to pollu
