(2008)]. The effects of using dolomite and waste marble powder as partial replacement of cement on the mechanical properties of concrete was investigated [Ali Ergun (2011)]. Test results indicated that the optimize amount of dolomite and WMP as replacement by weight of cement had the best compressive and flexural strengths.
