| Abstract | ||
| The aim of this study is to find the influence of different fibers parameters such as volume, aspect ratio, type, and shape of fibers on the workability of the fresh concrete and some of the mechanical properties of selfcompacting concrete made from locally available materials. One reference concrete mix, which all other mixes develop from, has been designed in this work. The results indicate that the addition of fibers decreases the slump flow, increases T50., decreases L-box flow and increases Tv. The effect of fibers on the fresh properties of SCC depends on the content, length, type and shape of fibers. Steel fibers had a marginal effect on compressive strength of FRSCC, the higher percent of increase in compressive strength was (2.38 %). All fiber mixes demonstrated higher splitting tensile strength, flexural strength and impact strength relative to plain mix at all curing ages. The strengths increased as the fiber content and/or the aspect ratio increased and it increased by using crimped fibers. The fibers slightly decrease the U.P.V at 28 days. | ||
