The study which is involved in this research paper with partially replacement of Red-Mud in cements. By reading many research papers I found that many authors has commonly shown the mix design for M30 concrete mix. There are various tested has been done which compressive strength, split tensile strength and flextural strength. The author has different percentage of replacement of Red-Mud has done with cement. But commonly 15% has increased in all the three types of test and there are different results in there research.
