Abstract

The engineering properties of high-strength concrete are significantly different from those of ordinary concrete, and as a result, this concrete has become popular in a variety of applications, including the construction industry, particularly for tall buildings, bridges with long spans, and precast members. Reinforcing high-strength concrete using fibers is a common method for increasing ductility without losing strength. In this study, steel fibers were employed to replace 1, 1.5, 2, and 2.5 percent of the total volume of concrete, and a total of 5 mixed designs were conceived and constructed. The findings showed that the addition of steel fibers up to 2% by volume boosted the compressive strength and decreased at 2.5% by volume. The incorporation of steel fibers has diminished the mixes' durability.
