The development of Self Compacting Concrete (SCC) by Professor Hajme Okamura in 1986 has made a remarkable impact on the construction industry by overcoming some of the problems associated with fresh concrete.SCC homogenously spread under its own weight without any additional compaction and does not entrap air.It improves the efficiency at the construction site enhances the working conditions and also the quality and appearance of concrete. For such applications the fresh concrete must possess high fluidity and good cohesiveness. The use of fine materials such as fly ash can ensure the required concrete properties.
In this present study the results of experimental program aimed at producing and evaluating SCC according to Nan su mix design and also a conventional concrete using ACI method. To qualify the developed SCC mix fresh properties like slump flow, J-Ring, V-funnel, L-flow tests were conducted and checked against EFNARC specifications. Then this mix is further modified based on packing factors (PF) varying from 1.12 to 1.18. The fresh and hardened properties of the new mixes were also validated to the satisfaction of EFNARC guidelines.[3] Then a relative study on the variability of the mechanical properties like compressive strength and split tensile strength were examined at 28 and 90 days of normal curing and with the mechanical properties of conventional concrete.
