초록

Recently, a growing attention is paid to development of new construction materials. The fiber reinforced Concrete is recognized as one of the most promising new construction materials. A comprehensive experimental study was conducted to explore the mechanical behavior of steel fiber reinforced concrete. The major variables in the experiment were the fiber contents and the lengths of steel fibers. The flexural, tensile, and compressive behavior of steel fiber reinforced concrete were investigated. The present study shows that the strength and ductility are remarkably increased with the increase of fiber content. The rate of strength increase due to steel fibers was found to be the highest in tension, the middle in flexure and the lowest in compression. This indicates that the steel fibers play a major role in increasing the tensile capacity.
