Abstract
This paper aims to study the flexural strength of reinforced concrete (RC) beam containing steel fiber under chloride environment with cyclic wetting and drying. The compressive strength, splitting tensile strength of concrete containing steel fiber were also studied. Steel fiber was used at the content of 0.50% by volume of the concrete. The compressive strength and splitting tensile strength and were tested at the age of 28 days. The flexural strength test of the RC beam was done after the cyclic wetting and drying period of 2 years in the 5.0% of chloride solution. From the experimental results, it was found that the compressive strength of concrete containing steel fiber was similar to control concrete. The splitting tensile strength of concrete mixed with steel fiber was higher than that without steel fiber. The flexural strength of RC beam with steel fiber was higher than that without steel fiber. The flexural strength of RC beam exposed to chloride environment was lower than that exposed to the water.
