Monitoreo mediante Emisión Acústica de vigas de hormigón de alta resistencia con y sin fibras expuesto a alta temperatura

ABSTRACT The addition of fibers to the cementitious matrix, giving rise to fiber-reinforced concrete, aims to improve the low ductility observed in concrete mechanical response under different load scenarios, particularly under direct tension. In this work, cracking and mechanical degradation processes of concrete elements using acoustic emission technique are examined, with the objective of analyzing the incidence of high temperatures on the failure behavior of high-strength concrete beams with and without fibers. Results of an experimental campaign including different mechanical tests on con...
