With ever-growing population and expanding urban centers, increased levels of construction are expected in the forthcoming years in our developing country. Due to enhanced mechanical properties such as strength, stiffness, toughness, ductility and durability, high performance concrete has gained wider acceptance in the construction of tall buildings, long span bridges, off shore structures and other mega structures. For past few decades, HPC has undergone many developments based on the influence of cement, type and proportions of mineral admixtures, types of super plasticizer and the composition of coarse and fine aggregate. It is commonly accepted that the properties of aggregate used in HPC have great influence on structural properties and on durability.
