Abstract

The present study investigates on the split tensile strength of concrete with partial replacement of cement by fly ash and metakaοlin (mineral admixtures) of M40 grade concrete. At different proportions of mineral admixtures the concrete cylinders were made, tested and compared in terms of split tensile strength with the conventional concrete (0% fly ash and 0% metakaοlin). The tests were conducted after 7days and 28 days curing. The optimum percentage of adding fly ash and metakaοlin was determined to be 30% and 15% respectively. This combination showed the maximum improvement in split tensile strength.
