Evaluation the influence of steel-fiber on the concrete characteristics

Abstract

The 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.

Analysis of fibre reinforced concrete for road pavements on very weak soils

“…It was determined that the workability of concrete reinforced with fibres decreases with an increase in fibre volume, especially after the rate of 0.75 % steel fibre, and the degree of slump entered the S3 consistency class at the rate of 1.50 % steel fibre. The results of the current study are compatible with those in the literature [31], as it has been observed in the literature that the workability of concrete mixtures decreases after a 0.8 % steel fibre ratio in studies using different ratios of steel fibres [32,33].…”

Study The Behavior of Square Reinforced Concrete Columns Strengthened with CFRP

“…There is a current demand for strengthening numerous reinforced concrete (RC) structures, particularly in developing nations (Al-Khafaji et al, 2021;Ali et al, 2022;Falah et al, 2020). The process of demolishing old buildings and constructing new ones is both financially burdensome and time intensive.…”
