Análisis de la influencia del módulo de elasticidad de los agregados gruesos en el módulo de elasticidad del hormigón

Abstract

All buildings from the engineering point of view need a structural design, the objective is to save lives and reduce material damage, currently the vast majority of buildings are still built in reinforced concrete, so they must resist the last efforts of flexo compressions produced from a structural calculation. Within the equator, the regions of the coast and mountains are the areas of greatest seismic risk, generally the efforts coming from this are the greatest. Before building, it is necessary to design, therefore, reference values of the properties of the materials are taken, properties that the engineer seeks to replicate during the work, one of these properties is the modulus of elasticity that depends both on the resistance of the concrete and also on the the quality of its aggregates. The present investigation obtains the modulus of elasticity of concrete through ASTM C 469 - 02, the modulus of elasticity of rocks located in Mulaló, Latacunga - Cotopaxi and Guayllabamba, Quito - Pichincha through the standard ASTM D 3148 - 96. To then compare them with the proposals in the Ecuadorian Construction Standard NEC-SE-HM of 2015
