Abstract:

This paper reflects self-compacting concrete which is developed using modified Nan-Su mix design. Slump flow, J-Ring, V-funnel tests are conducted to justify the fresh properties of SCC and are checked. Cubes of 150x150x150mm size casted in which 15 cubes are SCC without Nano silica and 15 cubes are of each 1 %, 1.5% and 2% of Nano silica (colloidal state with 16% and 30% Nano content). In order to get relative idea about the compressive strength and durability properties of SCC, axial compression test on cubes for 7 days and 28days of curing in water were done and also cubes were immersed in 5% HCl and 5% H₂SO₄respectively. Sorptivity test has also been conducted to assess durability of SCC. Test results indicate that use of Nano Silica in SCC has improved the performance of SCC in strength as well as in durability.
