Thermal activation is a phenomenon that can reduce or liquidate destruction of high-calcium ashes of thermal power plants by obtaining a nonequilibrium alite in them, which creates new opportunities for obtaining clinker cements. Discovery of thermal activation provides an alternative to a very capital-intensive and costly in operation technology of cement manufacturing in furnaces with cyclone heat exchangers. It is essential that the production of nonequilibrium clinker at TPP eliminates the need for storage of ash and slag, providing, along with thermal and electric energy generation, the production of a high-strength binder with accelerated hardening times, i.e. implements the concept of nonwaste TPP. The cost of producing energy-cement, in comparison with cement plant, is 40-60 % lower, because ash and slag, being a product of the thermal process, have a favorable chemical composition. An additional energy resource of ash is the carbon residue ranging from 5 to 10 %, which takes part in agglomerating process as a charge fuel. Another 60-40 % necessary for ignition of clinker charge can be obtained in the form of boiler fuel burned in boilers.
