La acumulación de este material se considera un problema ambiental en las comunidades que producen esta bebida espirituosa de forma artesanal. Este residuo contiene fibras óptimas para su uso como material de refuerzo, obteniéndose un valor agregado y reduciendo la contaminación ambiental. En el desarrollo de un nuevo material, se necesita conocer sus propiedades mecánicas. Para saber si el nuevo material es factible, una de las propiedades más importantes es la resistencia a la compresión. Para este trabajo se tuvo como objetivo determinar la resistencia a la compresión de un material biocompuesto de matriz cemento/tepexil, reforzado con fibras de bagazo de agave. Para la obtención del material, las fibras fueron lavadas con agua con una hidrolavadora, secadas a la intemperie durante 7 h y molidas en un molino de cuchillas a 1 mm de longitud. Posteriormente, se trataron con una solución acuosa de hidróxido de calcio al 10%, durante 34 h. Se realizaron cinco distintas formulaciones con diferentes proporciones de fibra/tepexil. La resistencia a la compresión se midió en una máquina universal Geotest a 7, 14 y 28 días. Se observó que en el aumento de la proporción de fibras hay una disminución en la resistencia a la compresión y densidad del material biocompuesto. La proporción óptima de fibras fue de 1:0:1 (cemento Portland:tepexil:fibra), con una resistencia a la compresión de 6.19 MPa y una densidad de 1 366.73 kg/m3 a los 28 días.]]></p></abstract>

The accumulation of this material is considered an environmental problem in the communities that produce this spirit drink in an artisanal way. This waste contains optimal fibers for use as reinforcement material, obtaining an added value and reducing environmental pollution. In the development of a new material, you need to know its mechanical properties. To know if the new material is feasible, one of the most important properties is the resistance to compression. For this work, the objective was to determine the compressive strength of a biocomposite cement/tepexil matrix material, reinforced with agave bagasse fibers. To obtain the material, the fibers were washed with water with a pressure washer, dried in the open for 7 hours and ground in a knife mill to 1 mm in length. Subsequently, they were treated with an aqueous solution of 10% calcium hydroxide, for 34 h. Five different formulations were made with different proportions of fiber/tepexil. The compressive strength was measured on a Geotest universal machine at 7, 14 and 28 days. It was observed that in the increase of the proportion of fibers there is a decrease in the compressive strength and density of the biocomposite material. The optimum fiber ratio was 1:0:1 (Portland cement:tepexil:fiber), with a compressive strength of 6.19 MPa and a density of 1 366.73 kg/m3 at 28 days.]]></p></abstract>
