In this paper, the study on growth of compressive strength in cement mortars blended with calcined-kaolin (MK) has performed. The preparation and Grinding of the kaolins was carried out at sistan cement factory. Calcination of clays was carried out in a kiln at central laboratory in S&B university.The blends produced were tested in the laboratory. Cement mortars containing 0, 5, 10 and 15% replacement of cement with calcined-kaolin and with a water/binder (W/B) ratio of 0.485 have been moist cured for periods from 3 to 28 days. Good results were obtained from the compressive strength tests, demonstrating the viability and robustness of this technology.
