The use of natural zeolites in construction industry is presented. Zeolitic tuffs have been used for thousands of years as light – weight, durable dimension stone. Starting from the end of 20thcentury natural zeolites found large utilization in building materials: in cement manufacture, in clay – cement mixtures, in stability agents for cement manufacture, for aerated concrete production. Geopolymers are a new fire, blast and dried resistance group of building materials. Clinoptilolite tuffs can be utilized for the production of geopolymers.
