EXPERIMENTAL STUDY ON STRENGTH PARAMETER OF STEEL FIBRE REINFORCED HIGH VOLUME FLY ASH CONCRETE

The main objective of this paper is to investigate the effect of steel fiber of M20 grade HVFA (High Volume Fly Ash Concrete) concrete with proportion 0.48 water cement ratio. Here cement is partially replaced by 75%, 80%, and 85% of F- class fly ash of by weight. Also dosage of steel fiber in percentage of 0.5%, 1%, and 1.5% by weight of concrete is used. Aspect ratio of steel fibre used us 60. Compression strength test, split tensile test were performed according to guidelines. The result were compared with results of control mix concrete. Due to addition ofsteel fiber Compression strength, split tensile strength has increased.
