The robustness of self-consolidating concrete (SCC) is enhanced by the addition of powder as well as viscosity modifying agent (VMA). The strength and durability properties of such combined powder and VMA type of SCC must be influenced by the reactivity of powder used and other mixture proportions. An attempt has been made in this investigation to study the influence of reactive silica fume and inert crusher dust as different powders in SCC. The SCC mixes were
designed for M25, M35, M45 and M55 grades and tested for fresh properties, compressive strength, split tensile strength, sorptivity and chloride ingress. It was observed that the SCCs with silica fume produced better strength and durability than the SCCs with crusher dust and the difference was remarkable.
