Abstract:
In the process of a long-term study of fine cementless mortar from wastes of thermal power plants (TPP) and other industries, aspects of its tech-nology were determined which were as follows: power 1. Processing slag (also known as bottom plant to sand of 0 to 5 mm size fraction. ash) from the Abakan thermal 2. Grinding fly ash to a fineness of 700 to 750 m2/kg with the use of mechanochemical activation process. 3. Using two - stage thermal treatment of cementless mortar mixture and determining optimal regimes for secondary thermal treatment. 4. Using a model method for concrete development. The application of cementless ash slag mortars non- load - bearing concrete profitability respectively. to load - bearing and
