Estimación del módulo de elasticidad del hormigón con agregados reciclados de adoquines Ibarra – Ecuador

Abstract

DOI: https://doi.org/10.46296/ig.v9i17.0325 Abstract This descriptive experimental research aimed to develop an equation to determine the modulus of elasticity for structural concrete with a compressive strength of 240 kg/cm2 incorporating recycled aggregates from waste pavers in Ibarra, Ecuador. Driven by the environmental issues regarding inadequate waste management and the need to adapt regulatory equations to local materials, the methodology involved material characterization and mix design following INEN and ASTM standards, substituting fine aggregate at percentages of 4%, 8%, and 12%. Tests conducted at 28 days demonstrated a direct relationship between the substitution level and elastic behavior, enabling the formulation of empirical equations that proved more accurate than the standard ACI 318-19 proposal, which exhibited limitations for these specific materials. Ultimately, it was concluded that incorporating up to 12% of recycled material is technically feasible without compromising compressive strength, validating a calculation tool that supports sustainable structural design and the valorization of construction waste in the regional context. Keywords: Structural concrete, modulus of elasticity, recycled aggregates, waste pavers, sustainable design, waste valorization.DOI: https://doi.org/10.46296/ig.v9i17.0325 Resumen Esta investigación experimental descriptiva tuvo como objetivo desarrollar una ecuación para determinar el módulo de elasticidad en hormigón estructural de 240 kg/cm2, incorporando agregados reciclados provenientes de adoquines de desecho de la ciudad de Ibarra, Ecuador. Motivada por la gestión inadecuada de residuos y la necesidad de ajustar las normativas a materiales locales, la metodología incluyó la caracterización de materiales y el diseño de mezclas bajo normas INEN y ASTM, sustituyendo el agregado fino en porcentajes del 4%, 8% y 12%. Los ensayos realizados a los 28 días demostraron una relación directa entre el nivel de sustitución y el comportamiento elástico, permitiendo formular ecuaciones empíricas que resultaron ser más precisas que la propuesta estándar del ACI 318-19, la cual mostró limitaciones para estos materiales específicos. Finalmente, se concluyó que la incorporación de hasta un 12% de material reciclado es técnicamente viable sin comprometer la resistencia a la compresión, validando así una herramienta de cálculo que favorece el diseño sostenible y la valorización de residuos de construcción en el contexto regional. Palabras clave: Hormigón estructural, módulo de elasticidad, agregados reciclados, adoquines de desecho, diseño sostenible, valorización de residuos.
