Análisis teórico-experimental de la resistencia a la compresión del hormigón y su influencia en el módulo de elasticidad estático en el cantón Santo Domingo de los Colorados, provincia de Santo Domingo de los Tsáchilas

Abstract

This research work was carried out by taking samples of stone materials from the "Brisas del Toachi" and "Copeto" mines using INEN 695 standards, then a sample reduction was made according to INEN 2566, continuing with the investigation of some physical mechanical characteristics indicated in INEN 872 in order to make a dosage for a structural concrete and determine the actual density of cement using INEN 156. The mix design was made for each mine with its respective dosage using the method of optimum densities for concrete compressive strengths of 210 and 240 kilograms over square centimeters. Once the dosages were obtained for each mine, concrete specimens were made for their respective curing using INEN 3124 standard; fresh concrete tests were carried out, such as: sampling INEN 1763; density, air content and yield INEN 1579, settlement INEN 1578; hardened concrete tests were carried out to determine the compressive strength at 3, 7 and 28 days INEN 1573. With this we have access to information that allows us to interpret and graph these values for a better understanding and analysis of them. Finally, the experimental MEE is determined by using the ASTM C469 standard and with this, the use of values for the factors exposed in the ACI 318-14 standard and its correct adaptation according to the use of the materials of the mines studied is proposed.
