The compressive strength of cement and, consequently, its physical properties could vary as a result of variations in the raw materials, as well as in manufacturing conditions. Therefore, an experimental study has been checked out herein by investigating the mechanical and physical properties of concrete specimens by means of four different types of Ordinary Portland Cements, namely Black Bull, Lucky, Pak Land and DG obtained from the market of Sindh Pakistan. Based on obtained results, it was found that Lucky cement type performed well when compared to other three types both in compressive and tensile strength of concrete. Although there were some differences in the physical properties of cement used in this study, however, they all meet with the requirements of international standards.展开更多
