Study of binding properties of the products of dehydration of phosphogypsum
The paper presents the results of the research on the effect of the firing temperature on the binding properties of the products of dehydration of phosphogypsum. It was found that the products of dehydration of phosphogypsum taken from dumps have mild astringent properties. Anhydrite binder obtained by calcining phosphogypsum at 900-1000 ° C is fast setting and high strength.
