The problem of using natural zeolites and utilization of spent sorbents-zeolites used in industrial water purification processes is considered. The promising possibility of their use as additives in the production of cement and concretes, as additives to Portland cement, is shown. Zeolites are crystalline aqueous aluminosilicates containing as cations elements I and II groups of the periodic table, in particular sodium, potassium, magnesium, calcium, strontium, and barium.
