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.
