The Self Compacting Concrete (SCC) is a type of concrete that gets compacted under its own weight. The present paper is an experimental investigation on the strength and creep characteristics of different mixes of High Strength Self Compacting Concrete (HSSCC). HSSCC mixes were prepared using Ground Granulated Blast Furnace Slag (GGBFS) and Alccofine as mineral admixtures. Trial mixes were carried out for three different grades namely M 60, M 80 and M 100. The rheology of mixes was obtained by varying both water–binder ratio and the dosage of superplasticizer. The properties of fresh HSSCC such as flowability, passing ability and filling ability were evaluated as per EFNARC 2005 with tests on Slump Flow, T500 Slump, V Funnel Flow Time and L Box. The cube specimens of 150 mm side were cast and cured as per the standard codal procedures. The compressive strength of the mixes at a curing period of 28 days was assessed as per IS 516:1959 (reaff. 2013), recorded and analysed. The cylindrical specimens of 150 mm dia. and 300 mm height were cast to measure creep as a durability parameter of HSSCC. From the analysis of results, it was observed that the workability and strength of mixes get enhanced due to the presence of GGBFS and Alccofine as mineral admixtures. The resistance to creep strain of HSSCC, in comparison with that of normal SCC, is found to increase with the increase in the grade of HSSCC (from M 60 to M 80 and from M 80 to M 100). The range of creep strain obtained varied from 450 microstrain M 100 to 1350 microstrain M 60. Hence it may be rationally concluded that the addition of GGBFS and Alccofine in concrete increases the durability (creep characteristics) of HSSCC.
