dc.descriptionThe reinforcement system of concrete structures using composite materials has been widely used for more than fifty years. However, there are still many unknowns regarding their longterm behavior, as the control of the bond between the concrete and the reinforcement materials being essential to ensure their quality. It is a reinforcement system that is made by adhesion, and as consequence of the uncertainty on the adhesion tension, in practice, it is solved with anchorages that make the work more expensive and which are not feasible for large areas of reinforcement. A correct installation that guarantees the proper behavior of the reinforcement materials would optimize this type of strengthening system and its applicability. The implementation of an appropriate quality control plan guarantees the optimization of the system and allows to establish the proper maintenance criteria. This research presents an experimental program for the quality control of laying, based on the study of the bond between the concrete and fiber composite sheets, taking into account different types of concrete and surface preparation techniques. An in situ quality control plan with semi-destructive pull off and non-destructive ultrasonic type tests allows verifying the effectiveness of the reinforcement.eng
dc.descriptionEl sistema de refuerzo de estructuras de concreto mediante materiales compuestos se emplea de forma intensiva desde hace 50 años. Sin embargo, aún son numerosas las incógnitas respecto a su comportamiento a largo plazo, por lo cual es fundamental el control de la unión entre el concreto y el refuerzo para asegurar su calidad. Es un sistema de refuerzo que se realiza por adhesión, y como consecuencia de la incertidumbre sobre la tensión de adherencia, en la práctica se resuelve con anclajes que encarecen la obra y que resultan inviables en grandes superficies de refuerzo. Una correcta puesta en obra y con garantías del adecuado comportamiento del refuerzo optimiza y valoriza este sistema. La implantación de un plan de control de calidad apropiado garantiza la optimización del refuerzo y permite establecer los criterios de mantenimiento adecuados. En esta investigación se ha desarrollado un plan experimental para el control de calidad de la puesta en obra, basado en el estudio de la unión entre concreto y las bandas de refuerzo, teniendo en cuenta diferentes tipos de concreto y sistemas de preparación superficial. Un plan de control de calidad in situ con ensayos semidestructivos tipo pull-off y no destructivos tipo ultrasonidos permite verificar la efectividad del refuerzo.spa
