RESEARCH OVERVIEW
Abstract
The paper presents the results of studies on the neutralization of water-soluble PO4-3 ions in phosphogypsum, which have a negative effect on the properties of gypsum binder. The results of physical and chemical studies of phosphogypsum and metallurgical slag are presented. The use of iron-containing additives can also improve some physical properties of the final product.
It has been established that neutralization of water-soluble PO4-3 in phosphogypsum using Fe2+ and Fe3+ ions is a promising method that not only improves the quality of building materials but also solves environmental problems associated with phosphogypsum disposal.
