Abstract:

Plain Portland cement concrete is a brittle material. The strength of concrete in tension is much lower than in compression. A growing tensile crack in plain concrete can very soon lead to failure. In the presence of reinforcement, the tensile load is transferred to the steel. An alternative to increasing the load carrying capacity of concrete in tension is the addition of fibers. Well dispersed fibers in concrete act to bridge the cracks that develop in concrete. The incorporation of fibers in a cement matrix leads to an increase in the toughness and tensile strength, and an improvement in the cracking and deformation characteristics of the resultant concrete. An attempt has been made to investigate the influence of crimped steel fibers of aspect ratio 60 on the compressive and split tensile strength for M20 grade of concrete. Few Regression Models were deduced to estimate the strengths for CSFRC with respect to curing period and percentage of fiber. Conclusions are made by comparing the experimental and analytical results.
