Abstract

This research examines how reinforcing pure gypsum with steel fiber (SF) changes its compressive strength. Six pure gypsum-only mixtures will be used in the study. There are two groups of these mixtures, with water-to-gypsum ratios of 0.6 and 0.7, respectively. Steel fiber volume fractions of 0 %, 0.15 %, and 0.3 % were used to subdivide each group into three subgroups further. For every group, three samples were taken in 50x50x50 mm cubes. Steel fibers added to pure gypsum mixtures were shown to boost compressive strength for both water/gypsum ratios, with the percentage increase increasing with the water/gypsum ratio. However, the compressive strength decreases for all volume fractions of steel fiber as the water/gypsum ratio rises.
