• at the Norilsk Mining and Metallurgical Combine cementing and slag fillers for general construction purposes were put into practice;
• in cooperation with the Mining Institute of the KSC RAS there were developed and introduced the filling mixtures compositions for the Pechenganikel Combine and other enterprises of the Murmansk region;
• the technology for obtaining glazed concrete was used at the Murmansk house-building combine;
• technological regimes for stone processing developed with the assistance of the Laboratory of Mineral Raw Materials and Silicates Synthesis have been used at the 4 stone processing enterprises of the Murmansk region;
• there was developed the technology of arbolite production on the basis of mineral binders and light wood waste of local woodworking enterprises;
• there was developed the technology for the production of bricks, tiles and decorative products using low-melting clays of the Kola Peninsula and wastes of ore processing; - there were obtained decorative glazed coatings from local mineral raw materials ;
