A Comparative Study on Compressive Strength, Split Tensile Strength and Flexural Strength of SCC of grade M40 containing Coarse aggregate of Size less than 6mm

Concrete is a brittle material. It is good in compression and weak in tension. Strength of concrete means the compressive strength of concrete of 150mm cube at 28 days. The quality of concrete is depicted by its compressive strength. The other strength such as flexural strength, split tensile strength are all ultimately depends on compressive strength of concrete. The strength of concrete never depends on strength of aggregate or the strength of the cement mortar matrix. But it depends on the interfacial transition zone except in light weight aggregate concrete. Here an attempt is made to test SCC for all three above said strengths and the behavior of SCC of grade M40 with silica fume and without silica fume is tested. The advantage of using aggregate of 6mm and less is justified with the amount of cement and its compressive strength.
