Description

technical field

[0001] The invention belongs to the technical field of building materials, and also relates to the technical field of functional materials, in particular to a desulfurized gypsum-based functional type compound composed of desulfurized gypsum, slag micropowder, quartz sand, diatomite, nano-titanium dioxide, chemical additives, etc. Plastering mortar and preparation method thereof. Background technique

[0002] With the development of my country's economy, the resource utilization of solid waste has been paid more and more attention. Desulfurization gypsum is a solid waste produced in the flue gas desulfurization process of coal-fired power plants, and has become the second largest solid waste except fly ash; nearly 100 million tons of wet flue gas desulfurization gypsum are produced in my country every year. Storage not only takes up a lot of land, but also pollutes the environment and land. Therefore, the utilization and research of industrial solid wastes s...
