“…Accordingly, the authors recommend investigating the effect of SCM such as fly ash, ground granulated blast furnace slag, metakaolin, silica fume, rice husks ash, waste paper, [29], [30], [39], [40], [31]- [38] and other SCMs [41]- [45] commonly used as substitutes for the cement to investigate their impact on the service life of bridges and thus including them in future structures. In addition to that, the use of industrial waste or by-products [33], [46], [55]- [59], [47]- [54] is considered a worthy topic in improving concrete technology in general from an environmental perspective and towards sustainability.…”

The concrete structures deterioration in the last few decades required effective methods for evaluating and maintaining the structure condition. Currently, assessing the performance and safety of reinforced concrete (RC) structures relies on routine-based visual inspection (VI). However, there are another non-destructive test (NDT) technique that can provide a more accurate assessment of the structures. Thus, in this study, a footbridge located in Liverpool, UK is chosen as a case study and has NDT techniques used for assessment. The main objective of this research is to determine the condition of structural bridge components and investigate its level of defect and deterioration using non-destructive tests. The methodologies involved are visual inspection, and NDT techniques include the rebound hammer, cover meter, Moisture Content & Depth of Carbonation Testing, Chloride Testing and Half Cell Test. The framework, when implemented with the best selection of NDT techniques, helps in determining the level of defect and deterioration of the structural bridge components and next recommendation regarding the condition of the bridge. The involved bridge structural components include column, deck, wall and staircase. Findings from the visual inspection show that there were many defects and deteriorations found at the structural bridge components, which includes crack, spalling, and delamination and rusting. Further, NDT techniques that were carried out at the selected bridge structural part shows that some of the components exhibited a moderate risk of corrosion and acceptable concrete surface quality. In general, further maintenance is needed specifically to some critical structural components of the bridge.
