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.
