Item Análisis del módulo de elasticidad estático del hormigón en base a su resistencia a la compresión, fabricado con materiales de las minas: Comanche Uno y Comanche Dos, ubicadas en el cantón Palora, provincia de Morona Santiago(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2022-03) López Kayuk, Lizbeth Aracely; Núñez Aldás, Galo WilfridoThis experimental work began with a visual inspection and sampling of fine and coarse aggregates from the "Comanche Uno" and "Comanche Dos" mines, continuing with the process, a reduction to test size was carried out. Once the samples were obtained, the characterization tests of the aggregates began in the laboratory with the aim of knowing their physical-mechanical properties and with the data obtained designing the concrete mixtures, using the method of optimum density for compressive strength. at 28 days of age at 21 and 24 MPa. To continue with the process, cylindrical specimens were made, simultaneously with this process tests were carried out on fresh concrete, as well as: determination of settlement, density, performance and air content. Tests were also carried out on the concrete in the hardened state, such as the determination of the compressive strength at 7, 14, 21 and 28 days of age and the test for the determination of the static elasticity modulus, which is carried out at 28 days old. The static modulus of elasticity was determined experimentally in accordance with ASTM C469 and theoretically in accordance with ACI 318. To conclude with the experimental work, the analysis and comparison of results was carried out.
