Efecto del uso de fibras de caña de azúcar y virutas de metal en concreto hidráulico

This study evaluated the effect of using sugarcane bagasse and lathe steel shavings—two recycled materials—on the mechanical properties of concrete, focusing on compressive and flexural strength. Concrete mixes were prepared with fiber contents of 0.75% and 1.5%, and compared to a control mix without fibers.The experimental results showed that sugarcane bagasse, due to its high porosity and water absorption capacity, significantly reduced concrete strength, especially at higher concentrations, interfering with the cement hydration process. In contrast, lathe steel shavings, owing to their rough, inorganic texture, exhibited better adhesion to the concrete matrix and lower strength losses compared to bagasse. However, both types of fibers resulted in decreased performance relative to the control mix. The study concludes that steel shavings are a more viable reinforcement material and highlights the need to optimize fiber proportions and pre-treatment methods to enhance structural performance while also promoting sustainable solutions through the reuse of industrial and agro-industrial waste.
