Overall results of the experimental study indicate that both offshore sand and quarry dust is a viable
alternative for river sand as fine aggregate of self-compacting concrete. Based on strength quarry dust is
found to be the better fine aggregate type for self-compacting concrete. Reason for higher strength in
quarry dust can be attributed to the possible better bond between the aggregate and cement paste. SCC
mixes has recorded different trend for the water required under the constant doze of viscosity modifying
agent and compressive strength compare to normal concrete mixes. Study with particle size distribution of
the different aggregate manipulated to a single particle size distribution reveals no significant change in
strength between the mixes with natural particle distribution and single particle distribution. This means
that the particle size distribution has only secondary influences on the SCC.
