Abstract
Raw material composition plays an essential role on the lining life of cement rotary kiln.They are obtained from hard rock quarries that represent the first step in the cement manufacturing process. That raw materials are transported to Al- Kufa cement plant then crushed and ground to very fine powder and then blended in the correct proportions.This research aims to study suitable rations of raw materials to produce cement in al Kufa cement plant in Iraq. Through a software program, suitale raw materials ratios for the clinker were estimated, then chemical and physical tests for clinker and cement according to Iraqi Standard Specification were done to recognize the effects on the properties of cement such as the ratios of major and minor oxides, Lime saturations factor (LSF), Silica Modulus (SM) Alumina Modulus (AM), compressive strength, setting time and soundness.
