Concrete Modulus of Elasticity Based on Compressive Strength Made with Materials of San Roque Mine Located in Imbabura, Ecuador

Abstract

Static Modulus of Elasticity of Concrete is used to control the displacements and deformations in reinforced concrete structures. Static Modulus of Elasticity of Concrete depends mainly of the modulus of elasticity of the aggregate. The ACI code establishes that static modulus of elasticity of a normal weight concrete is taken by using concrete compression strength. In this study, reinforced concrete specimens were made using aggregates obtained from the San Roque mine located in the province of Imbabura, Ecuador. Modulus of elasticity was obtained using ASTM C 469 method. The results showed that the ACI method to calculate the static modulus of elasticity of concrete is not applicable for those made with aggregates obtained from the San Roque mine.
