The present study highlights on the strength and drying shrinkage behavior of High Strength Self-Consolidating Concrete (HSSCC) mixes, are studied through experimental investigation. HSSCC mixes of M60, M80 and M100 are produced using Ground Granulated Blast Furnace Slag (GGBFS) and Alccofine as mineral admixtures. The IS 10262-2019 was adopted to design the mixes of HSSCC. The HSSCC are evaluated using tests on Slump flow, T500 slump flow, V funnel and L Box test. The strength parameters such as compressive strength and split tensile strength at period of moist curing are evaluated. For each mix proportion of HSSCC, three prism specimens of 75 × 75 × 150 mm were cast for drying shrinkage measurement and three cubes of 150 mm size were cast for water permeability measurement. The results have shown that shrinkage strain of HSSCC increases with the increases with powder content increases in the mix. Total powder content increases in the mix and shrinkage strain of concrete mixes was found to increase with time up to around 28 days and beyond which no appreciable increase was observed. The shrinkage result was in the range of 300–600 microstrain. As powder content in the mix increases, the depth of water penetration in specimens was found to reduce.
