Abstract
The use of Self Compacting Concrete (SCC) is increasing day by day in India and many infrastructure projects are going in for SCC, the example being ‘The Signature Bridge’ on river Yamuna near New Delhi and the BandraˇWorli sea link project, Mumbai The effect of Portland Slag Cement (70%) and GGBS (30%) on compressive strength of different grades of SCC Mix is not investigated as per the literature cited. The present investigation finds the effect of above proportion on compressive strength of SCC Mixes.
The modified Nan-Su mix design for application to PSC concrete is used. The workability properties Slump Flow, J-Ring, V- Funnel and L Box values satisfy EFNARC Guidelines. For all grades compressive strength obtained is less than the target mean strength. For M35 and M40 grades compressive strength is less than the characteristic compressive strength of concrete.
