Influence of Particle Size of Fine Aggregate on Filling Ability and Segregation Resistance of Self-Compacting Concrete

Abstract

This paper presents the study of influence of particle size of fine aggregate on the filling ability and segregation resistance of Self Compacting Concrete (SCC). The filling ability was assessed from the results of mortar spread diameter by mini truncated cone and the segregation resistance was assessed from the results of mini V-funnel flow time of mortar fraction of SCC as per EFNARC guidelines at 0, 15, 30, 45 and 60 minutes of mixing. 8 mixes of mortar fraction of SCC consist of two different cement replacement percentage (CRP) by fly ash are investigated for four different particle sizes of fine aggregate.
