ABSTRACT
Conventional concrete tends to present a problem with regard to adequate compaction in thin sections or areas of
congested reinforcement, which leads to a large volume of entrapped air voids and compromises the strength and durability of the
concrete. Self-Compacting Concrete (SCC) can minimize this problem since it was designed to compact under its own mass. For
such application, the fresh concrete must possess high fluidity and good cohesiveness. The aim of the study is to investigate the
flexural behavior of self compacting concrete (SCC) beams using steel fiber along with an addition of super plasticizer as
admixture. It is proposed to use of steel fiber materials in the fresh concrete M30 grade 0%, 0.5%, 1%, 1.5% replacement of
cement. Tests on fresh concrete were done to determine its workability. In this investigation, the properties of self compacting
concrete with or without steel fibre concrete were determined by conducting slump flow test were determined. It is found that the
compressive strength of SCC with 1% of steel fibre have 45.04N/mm2 which about 17% more than M30 grade concrete and the
tensile strength of SCC with 1.5% of steel fibre have 4.41N/mm2 which is about 18% more than ordinary concrete.
