The Raw materials are of great importance for producing a high-quality Portland Cement. Calcium, silica, and alumina are essential components of the initial mixture used for the manufacture of the Portland Cement.  The marl bed in the Euphrates Formation at the quarries of the Kufa cement plant was proposed to be an alternative raw material to provide such components to the cement mixture. For this reason, nine boreholes were drilled in addition to three boreholes that had been previously drilled in the study area. The marl reserve was classified according to the Russian classification as a C1 category, and as a probable reserve according to the British classification and estimated as a reserve of 53 million tons by using the triangle method. Porosity (30.47%), Bulk density (1.73 gm/cm3) and compressive strength (3.59 N/m2) were measured and show the homogeneity of hardness can serve in the reduction of the electrical energy consumption and the wear of equipment productivity and increase the production of the mills, that are reflected eventually in the reduction of the final product cost.
