Abstract: “In this paper, a brief practical review is presented on two grades of concrete of which one is medium strength concrete(M40)and the other is high strength concrete(M60), containing some mineral and chemical admixtures by mass of the cementitious material. The behavior of specimens cast with medium strength concrete and high strength concrete with and without admixtures are compared with respect to ultimate strength, workability and cracking. Strength improving admixtures such as CERAPLAST-400, CERAPROOF-PXL are applied for concrete mix to develop strength.”
