Abstract

In the present studies, results of an experimental investigation carried out to evaluate the fresh and hardened properties of
various mixes w ith varying fine aggregate and coarse aggregate proportions is presented. The fresh properties for filling, passing and
segregation resistance are monitored as per EFNARC guidelines w hile hardened properties namely the early age compressive strength
development of various specimens for a selected refrence mix is evaluated. The mix proportion of self compacting concrete has a constant
water-binder ratio of 0.31 and the super plasticizer dosage was kept 1.5 %. The total binder content is 585 kg/m3
. The concrete specimens
are cured by normal moist curing under normal atmospheric temperature. Early age strength was determined at 7 days. The experiements
were carried out varying the proportions of fine aggregates size particles between 600 micron to 2.36 mm and coarse aggregates of size
20mm and 10mm. The results show that there is considerable effect on the fresh properties and early age compressive strength of self
compacted concrete, due to varaiation in proportions of fine and coarse aggregates
