Physical and chemical characteristics of ashes formed at burning oil shale at temperatures 500, 600, 700, 800, 900 and 1030 °C were studied. Standard procedures were used to determine both pozzolanic activity and binding para­meters. The most suitable characteristics were provided with oil shale ash formed at 700 °C. Ashes (15 and 30%) were added to ordinary Portland cement. The optimum pozzolanic characteristics and performances were pro­vided by the mixture containing 15% ashes. The mixes meet the corres­ponding Turkish standards, and therefore, this oil shale can be used as an admixture in Portland cement.
