Item Análisis comparativo del hormigón simple y el hormigón con fibras de caucho reciclado de neumáticos como reemplazo parcial del agregado fino y su influencia en la resistencia a la compresión(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2023-03) León Merino, Alexis Sebastián; Ureña Aguirre, Maritza ElizabethFor many years the disposal of tires has been an issue that affects the world because it is one of the most difficult materials to degrade, so it is harmful to the environment. This project focuses on the use of concrete made with recycled rubber fibers as a contribution to the environment, where tests were carried out to demonstrate the increase in compressive strength. It began by subjecting the simple concrete and those containing the replacement of 5 and 10 percent of recycled rubber particles with a size of 2 to 4mm, to compression tests at the age of 7, 14, 21 and 28 days, where the resistance of the simple concrete reached a maximum value of 216.71 kg/cm2, while the group with replacement of 5 and 10 percent of rubber only achieved a resistance of 164.71 and 153.87 kg/cm2 respectively, with the group with replacement of 5 and 10 percent of rubber only achieved a resistance of 164.71 and 153.87 kg/cm2 respectively. 87 kg/cm2 respectively, thus reflecting that it did not have a higher resistance than the simple concrete, for which an extra experimental group was added that conserved the dosage of the simple concrete and added rubber fibers at 5 and 10 percent plus a plasticizing additive at 2 percent, where values of 227.16 kg/cm2 at 5 percent and 220.62 kg/cm2 at 10 percent were obtained, thus demonstrating a significant increase in resistance.
