This research investigates the performance of repair mortars using cement modified with 5% styrene-butadiene rubber (SBR) based on various properties, including spreading and wet density, mechanical strength (flexural and compressive), and transfer properties (total shrinkage). The mortars were further enhanced by the addition of vegetable and glass fibers at rates of 0.1, 0.3, and 0.5% relative to the total volume. The vegetable fiber employed in this study is hemp, which was pre-treated with 5% NaOH for 2 hours. Additionally, 10% silica fumes were used as a cement additive in all the mixtures. The findings demonstrate that the polymer mortar reinforced with 0.5% hemp fibers exhibited a notable increase of 14% and 9.5% in flexural and compressive strength, respectively, at 28 days when compared to polymer mortars without fibers. In terms of total shrinkage, mortars containing 0.3% or 0.5% hemp fibers showed superior long-term dimensional stability in comparison to those with glass fibers. These results strongly suggest that incorporating plant fibers, such as hemp, into cement materials modified by a polymer like styrene-butadiene rubber holds great promise for future applications.
