compressive strength and porosity are the three mechanical parameters of SCC which were discussed here. Density and compressive strength test conducted according to ASTM C 642-13 and ISO 1920-4: 2005. The 68-mm-diameter concrete samples were used for porosity test which was obtained from the centre of 100 mm cubes.5 4 3 2 1 5 1 1 5 2 2 5 90da ys 28 days 7da ys Compressive strength Nmm 2. 5 4 3 2 1 5 1 1 5 2 2 5 90da ys 28 days 7da ys.
