Item Evaluación del comportamiento a flexión de vigas de hormigón simple, preparado a partir de materiales reciclados(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2023-09) Sánchez Freire, Joseph Henry; Peñafiel Valla, Lourdes GabrielaConcrete is a material in high demand in construction, due to its excellent compressive strength and easy workability it is used on a large scale nationally and internationally and concrete rubble is produced which many times is not reused and Its main destination is a dump or ravines, which causes environmental damage. The main objective of this research is to analyze the flexural behavior of beams made from recycled concrete and to carry out an adequate dosage, previous laboratory tests such as granulometry, densities and moisture content have been carried out. A total of 36 beams have been made with different dosages of 10, 15, 30, 60 and 100 percent with a resistance of 240 kg/cm2 to obtain experimental results and compare them with base beams made from coarse natural aggregate, the beams After being cured at 7 and 28 days of age, they were flexurally tested and the loads (KN), modulus of rupture (MPa) and deflections (mm) presented by each of the beams were recorded. From the results obtained, the flexural resistance of each of the beams varies according to the percentage of aggregates that constitute them, showing that the modulus of rupture at 28 days of age, the VF_30 and VF_100 beams support greater flexural loads by 5.09 and 1.77 percent compared to base concrete VF_0 beams without recycled aggregate.
