The possibility of using of the “Norilsk Nickel” industrial complex waste instead of Portland cement and the solving problem of environment polution decrease is investigated in this work. It was determed that the dolomite waste, a big amount of which is accumulated in the dumps around the “Norilsk Nickel” industrial com-plex, burned till caustic dolomite was obtained and then mixed with the anhydrite can be used for the production of the cement free mortar. The granulated slag, which is the waste of nickel production plant, can be used as ag-gregate. The aggregate’s adhesion with the mortar can be enhanced by adding carphosiderite which is high disper-se galvanoplating waste. As a result the cement free mixture suitable for the filling of the gaps of mines can be obtained.
