| dc.description.abstract | Steel fibre reinforced concrete, SFRC, could be considered the little and unknown brother of the commonly known reinforced concrete. However, his trajectory has gone hand in hand with his elder brother during the development of these technologies and a promising future is foreseen. At the same time, the recent development of non-destructive testing techniques allow an easy and accurate quality control. This is crucial, since the main disadvantage of the SFRC is that it is not evident which the orientation of the fibres within the concrete matrix is once the concrete is hardened. Nevertheless, it is essential to overcome the laboratory level and to promote the study of real structural elements, so that materials are well received in the market.; Altzairu-zuntzez indarturiko hormigoia, AZIH (ingelesez SFRC), arrunki ezagutzen dugun hormigoi armatuaren anaia txiki eta ezezaguntzat har genezake. Hala ere, bere ibilbidea anaia zaharrenaren eskutik egin du teknologia hauen garapenean zehar, eta orain etorkizun oparoa aurreikusten zaio. Aldi berean, azken bolada honetan garatzen dabiltzan hainbat azterketa teknika ez-suntsikorrek, kalitate kontrol erraz eta zehatza egitea ahalbidetzen dute. Hori baita AZIHak duen desabantailetako bat, hau da, behin hormigoia gogortuta, ez da hain erraza zuntzek hormigoi matrizearen baitan hartzen duten orientazioa ikusten. Hala ere, materialak merkatuan harrera ona izan dezan, ezinbestekoa da laborategiko maila gainditu eta eskala errealeko egitura-osagaien ikerketa bultzatzea. | |
