The limestone can be used as mineral admixture in cement and concrete. When the limestone admixture amount is proper ( = 10% cement weight), the early strength of the blended Portland cement will be enhanced [1-3]. Limestone powder can also be used as mineral admixture in concrete for enhancing the early strength of concrete.
