Role of mineral additions in reducing CO2 emission

The influence of the substitution of a part of clinker with the mineral additions, in the process of production of mixed cement, on mechanical characteristics of cement and the reduction of CO2 emission is researched. Experiments are organized through the production of clinker, which has different phase structures, and cement, using different kinds and amount of mineral additions, with joint grinding and addition to the already ground cement. The most important of the effects analyzed, which include the reduction of thermal and electric energy, is the reduction of CO2 emission.
