Mortars are building materials used for various purposes such as for structural reinforcement. One of the great difficulties of this type of material is to maintain its parameters of workability without damaging its parameters of resistance to compression. Therefore, the objective of this work was to perform the incorporation of natural pineapple fibers into a 1:3 (cement:sand) mass mortar, without impairing its properties of workability and mechanical strength. Flow table, flexural tensile strength and compressive strength tests were performed on mortar containing 0, 2.5, 5 and 10% of pineapple fiber incorporation in mass. The results confirm that the mortar containing 10% significantly improves the mechanical properties but causes a high loss in the workability properties. Therefore, the proportion containing 5% of fibers is the most indicated because in addition to improving the mechanical strength does not affect the workability properties of the material.
