37 • A database containing data about natural radionuclides in technogenic raw material is expanded. It is determined that slag fractions contain 226Ra, 232Th and 40К. It is proved that slag has the first class of radioactive hazard, which means the lack of restrictions to use technogenic raw material in construction engineering. • Dump blast furnace slag Zaporizhstal exhibits high hydraulic activity with an increase in CaO absorption over time. – Zaporozhstal dump waste blast furnace slag can be recommended to produce binders: – Portland cement and Portland slag cement – in the totality of chemical parameters: relation to both moderately dangerous production wastes, the first radiation hazard class and high hydraulic activity.
