摘要：
This investigation is based on a newly developed method for extractive hemihydrate phosphogypsum waste usage by activating and neutralizing it in an acidic medium. The initial crystallic structure was destroyed by mechanical means and the acidic solutions in it was removed by neutralization i.e. by using alkali additives. As it was determined by experiments the developed gypsum cement binding material is water-resistance and can be used as a building material for production of various articles for use in exterior and interior applications.
