Determinación del módulo de elasticidad del hormigón en base a su resistencia a la compresión

Abstract

Concrete is one of the most flexible and easy-to-make building materials in the world nowadays, which is why it has become the most commonly used material in the world. Its main components differ in each place due to its specific characteristics, which are also responsible for the mechanical property changes. Understanding these properties is extremely important in order to provide engineers with the necessary information for dimensioning structural elements. Elasticity is one of the most important parameters in the design of concrete structures and its value depends on its components. Identifying its specific value is an essential step in guaranteeing the accuracy of the calculations and the structural design. This research aims to define the elasticity of concrete manufactured with aggregates and most widely used cements in the city of Azogues and its surroundings. The project involves carrying out tests on cylindrical hardened concrete samples to determine simultaneously the compressive strengths and the static elasticity of each sample. The tests will be performed according to the American Society of Testing Materials through the ASTM C 39 and ASTM C 496 standards. The results of the tests will allow to establish a correlation between these two parameters and to develop a similar equation to those of the Ecuadorian Construction Standard (NEC 2015) and the American Concrete Institute (ACI 318).
