Mechanical Performance and Durability of Date Palm Fibers Repair Mortar

Background: Concrete is the most widely used material in world after water. However, concrete could be damaged under aggressive environments and many structures require repair frequent maintenance. Readymade mortars with without synthetic fibers such as polypropylene acrylic are often mortars. The partial replacement of cement by supplementary cementitious materials use alternative natural agro-waste reduce environmental impact readymade Methods: This paper presents a comparative study between performance laboratory made ready-made were based on date palm local mineral additions (slag pozzolan). volume ratio addition was 0.75% content fixed at 15% replacement. Compressive strength, flexural shrinkage bond strength slant shear test tensile pull-off method investigated. durability mortar evaluated water capillary absorption. Results: results indicated that substitution improves but reduces compressive fiber-reinforced mortar. lowest values total shrinkage, absorption sorptivity observed for compared to vegetables fibers. Conclusion: mechanical performances comparable those
