Abstract: En esta tesis se presentan los resultados del comportamiento del concreto que incluye en la mezcla fibra de acero SIKA FIBER CHO 80/60 NB con relación al "concreto patrón". Se denomina "concreto patrón" a aquel concreto que no presenta fibra de acero. Se han efectuado análisis en diferentes dosificaciones de fibra de acero tales como 15 kg/m3, 30 kg/m3 y 45 kg/m3. Se han realizados las pruebas para 3 diferentes relaciones de agua/cemento: 0.40, 0.45 y 0.50. El concreto tuvo un asentamiento entre 3"-4" y se empleó cemento Portland Tipo I.
Para conocer las propiedades de los materiales empleados como el caso de los agregados grueso y fino, éstos fueron ensayados en el Laboratorio de Ensayo de Materiales de la UNI. Sin embargo, las propiedades del cemento y de la fibra de acero fueron considerados según las indicaciones de los fabricantes. El agua que se usó fue el agua potable del Laboratorio de Ensayo de Materiales.
Se realizaron ensayos del concreto en sus estados fresco y endurecido. Los resultados obtenidos en los ensayos de los concreto en estado endurecido evidencian la influencia positiva que ejerce la fibra de acero al concreto patrón en sus propiedades mecánicas. Para los casos de concretos con relación agua cemento 0.40 y 0.5 se ha logrado un incremento del orden del 9% en la resistencia a la compresión a los 28 días en comparación con el concreto patrón.
This thesis presents the results of the behavior of concrete that includes SIKA FIBER CHO 80/60 NB steel fiber in relation to the "standard concrete". Its is called "standard concrete" to that concrete that does not have steel fiber. Analyzes has been carried out on different of dosages of Steel fiber such as 15 kg/m3, 30 kg/m3 and 45 kg/m3. Tests have been performed for 3 different water/cement ratios: 0.40, 0.45 and 0.50. The concrete had a slump between 3"-4" and Type I Portland cement was used. To know the properties of the materials, coarse and fine aggregates, these were tested in the Materials Testing Laboratory at UNI. However, the properties of cement and steel fiber were considered according to the manufacturers indications. The water that was used was drinking water of the Materials Testing Laboratory. Concrete tests were performed in their fresh and hardened states. The test results obtained in hardened concrete show the positive influence that steel fiber exerts on the concrete in its mechanical properties. For concrete cases with a 0.40 and 0.5 of wáter/cement ratios, an increase of the order of 9% in compressive strength after 28 days has been archieved as compared to the “standard concrete”.
