Abstract

This paper deals with the results of an experimental investigation of the split tensile strength with steel fiber blended with the high strength concrete (M60). The fiber content varied from 0.5 to 5% by weight of cement at the interval of 0.5 %.Beams of 150mm x 150mm x 700 mm were tested for the flexural strength which was failed and broken in between middle third. The smaller broken piece was taken and tested for the split tensile test. A circulat bar of 6mm diameter was placed at a distance 150mm from the finished end and loaded till the failure and the tensile strength was found. Results and expressions by regression analysis are obtained. A significant improvement in the split tensile strengths is observed due to inclusion of steel fibers in the concrete
