Based on the available literature, a simple method was adopted to calculate the packing density and thereby reduce the void content of aggregates by optimising the packing of aggregates, by using two different sizes of coarse aggregates and fine aggregates. In this study provides an understanding on the way in which the shape of aggregates affects the properties of SCC. The fresh, hardened and durability properties of SCC with normal and lightweight fly ash coarse aggregates are compared. The mix with fly ash aggregates is found to have better fresh concrete properties due to round shape of aggregates. For the mix after packing of aggregates is found to have better mechanical and durability properties than all the other mixes.
