The quality control of concrete structures reinforced with external composite reinforcement

This article reviews the quality control (QC) of concrete structures reinforced with external composite reinforcement in the construction of bridges and overpasses. The study presents an overview of various methods of QC of carbon fiber sticking to study the application of carbon fiber in the construction industry and the main directions of development. The article considers four non-destructive testing methods that can assess the condition of an external reinforcement system without damaging the structure: ultrasonic flaw detection, pulse-echo, vibration diagnostics, and acoustic emission. To achieve this goal, theoretical methods were applied based on previously published works. The article considers the applicability of external reinforcement systems made of polymer composite as a load-bearing material in bridge structures. The study of the application of carbon fiber materials is based on the analysis of the literature. Basic QC methods can detect defects in composite materials such as delamination, voids, and cracks. The paper considered the applicability of carbon fiber and composites in construction, in particular, as an alternative to traditional structural materials such as steel. Regular use of SVA control methods helps to extend the service life of structures and reduce the risk of emergency situations, which is a key factor for the sustainable development of infrastructure and to ensure public safety.
