Cement quality in thermochemical clinker activation

Improving the quality of cement while reducing energy costs its production is one most important tasks industry. Cement properties are determined by hydration activity clinker minerals. In turn, minerals degree disorderliness crystal cell. The disorder cell depends on chemical composition minerals, type and concentration modifying additives. It also modes synthesis, both during firing cooling. An effective way activating intensive components raw mixture. This method can be carried out thermal activation calcium oxide, as well bilateral introduction in different zones rotary kiln polycomponent waste metallurgical industries morphology main mineral Portland clinker, alite, have been studied methods physical analysis. was found that crystals being formed characterized a nonstoichiometric composition. Their rapid growth accompanied impurity elements into mineral. clinkers conventional has determined. increase rate established, which leads to an strength characteristics 7-10 MPa.
