gypsum binder, phosphogypsum binder, modifiers, hardening, microstructure, X-ray phase analysis, electron microscopic analysis, ultrasonic method, specific resistance.

The structure formation of hardened samples of gypsum and phosphogypsum binders (with a complex of additives) is investigated by X-ray diffraction analysis and electron microscopy. The influence of additives-modifiers on the composition of curing products and on the morphology of the hydrate formation – CaSO4·2H2O – is determined. X-ray diffraction patterns and electron micrographs of hardened gypsum and phosphogypsum binders are shown.
