Evaluation the influence of steel-fiber on the concrete characteristics. Periodicals of Engineering and Natural Sciences, 10(3), 368-379.2303-4521https://hdl.handle.net/20.500.12939/3232The impact of steel fibers on the engineering characteristics of concretes were explored experimentally in this work. Steel fibers of 0.5, 0.7, and 0.9 percent by volume fraction were applied to concretes mixture with water/cements (W/C) proportions of 0.43 to accomplish this. There has been a total of 24 cubic specimens produced for compressive strengths testing, 24 cylindrical specimens for splitting tension strengths testing, and 12 cubic specimens for toughened unit weight testing. The experimental findings reveal that applying 0.5 percent to 0.9 percent of fibers made of steel to concrete boosts both compressive and tension strengths concurrently when compared to ordinary concretes; however, there is no discernible gain in hardened unit weight with increased fiber amounts.eninfo:eu-repo/semantics/openAccessEngineering CharacteristicsFresh and Hard ConcreteSteel-FibersArticle1033683792-s2.0-85146532483Q2
