Análisis comparativo del módulo de rotura en vigas de hormigón simple, vigas reforzadas con acero convencional y vigas reforzadas con fibra de carbono con una resistencia de 35 MPa

Abstract

Abstract: In recent decades, construction has been modernized through the use of fiber-reinforced concrete, with steel being the most widely used, despite its vulnerability to corrosion. In this regard. In this regard, Sanabria (2016) mentions that fiber is used to improve the resistance characteristics of construction materials, replacing corrugated steel bars due to the high cost of repairing reinforced concrete due to steel corrosion. This research attempts to study and verify the behavior of carbon fiber and steel, applied in steel-reinforced concrete beams, against carbon fiber reinforced concrete beams. With a concrete compression resistance of 35 MPa. The aggregates were obtained from the quarry, Boquerón Mina river "Arias & Cordova" (crushed material), from the Province of Loja. The materials used are based on NTE INEN standards. Finally, concrete beams were manufactured, checking their resistance using simple specimens, using Ø10mm rods made of conventional steel and carbon fiber. Both materials were found to be useful in withstanding flexion; With steel, higher strengths were obtained compared to carbon fibers and massive concrete, which is more brittle.
