Abstract
In this study, concrete material tests were carried out to investigate influence of steel fibers on variations of workability and strength characteristics of steel fiber reinforced high strength cementitious material, 100~150MPa of compressive strength, according to increase of fiber volume. Test specimens were arranged with eight levels of concrete compressive strength and fiber volume ratios, 0~7 vol%. The test results showed that there was little loss of flow in the inclusion of steel fibers from 0.0% to 4.0% in volume ratio of cementitious material. It means we can utilize micro steel fibers to produce high performance cementitious materials without the anxious of workability reduction. In addition, according to the inclusion of steel fibers, the improvements of mechanical performances were investigated. Not only tensile strength is improved by inclusion of steel fibers, but also compressive strength is highly improved.
