Abstract

Self-compacting concrete (SCC) is a new category of high-performance concrete that exhibits a low resistance to flow to insure high flowability and a moderate viscosity to maintain a homogenous deformation through restricted sections. In this paper, cement has been replaced by fly ash (FA) in various proportions from 10% to 60% or silica fume (SF) in proportions of 5%, 10% and 15% or combination from FA and SF by the proportions 25% FA + 5% SF, 20%FA+ 10%SF and 15%FA + 15%sf. Fresh properties based on the results of slump flow, L-box and V-funnel tests were measured while hardened properties based on the compressive strength, indirect tensile strength and flexural strength were measured. Tests results showed that fresh properties of all mixes satisfied the SCC requirements. The maximum strengths were attained at FA percentage of 20%while for SF this percentage was 15%. With the utilization of hybrid FA and SF, the maximum strengths were recorded at 20% FA + 10%SF. An increase in the compressive strength was recorded for all mixes with increasing age up to 270 days.
