Abstract:
For production of binding building materials in Russia and worldwide, used a variety of calcium-containing natural raw material: calcium carbonates, aragonite (CaCO3); sulfates-gypsum (CaSO4∙2H2O,CaSO4); oxides and hydroxides (bauxite glinozemservice); perforate-apatites and phosphates (Ca5∙(PO4)3∙F). The article discusses the need for air-conditioning of phosphogypsum to ensure that he was suitable without restrictions for processing into high-quality gypsum binders.
