The Study On Strength Characteristics Of High Strength Concrete Using Micro Steel Fiber

Abstract

This research paper deals with the strength improvement of M40 grade concrete by the addition of the micro steel fiber. The presence of micro steel fiber improves the physical properties of the concrete such as compression strength. The compressive strength test is carried out for the specimens using micro steel fiber and the results are analyzed. The fibers are added to the concrete in the proportions of 0%, 0.5%, 1%, 1.5%, 2%, 2.5%, 3% and 3.5% to the volume of the cement. The optimum percentage of micro steel fiber to give maximum compression strength was found to be 2.5%
