DEVELOPMENT OF CLINKER AND PORTLAND CEMENT COMPOSITION BASED ON SURKHONDARYO RAW MATERIALS

The purpose of this research work is to develop clinker and Portland cement compositions based on Surkhandarya raw materials for the planned construction of a cement plant, as well as to study their physical and chemical properties. The compositions of clinkers, including limestone, clay from the Yolgizbulok deposit and slag from the Almalyk mining and metallurgical plant, were studied. The optimal clinker composition was selected, on the basis of which Portland cement was obtained. The optimal amount of gypsum addition was determined to achieve a cement stone strength of 43,5 MPa. The developed clinker composition will provide the planned enterprise with local raw materials and will reduce the firing temperature by 5 °C, which will ensure energy saving in large-scale production. The resulting Portland cement grade 500 will provide the construction industry with high-quality building material.
