Assessment and Monitoring of Concrete Properties in Dam Construction: Practices in Turkey and Around the World [2026]

Concrete dams are hydraulic structures whose long-term safety depends on durability, thermal responsiveness, and time-dependent performance of the material, rather than only on initial strength. During their service life, concrete dams are affected by mechanical, thermal, fluid-related, and chemical factors. If these factors are not properly controlled, it may cause the concrete to deteriorate. This paper presents a state-of-practice comparative review based on the analysis of international standards, laboratory testing results, and operational monitoring practices, with a focus on analyzing performance gaps and decision-oriented implications for Turkish dam engineering practice. The mechanical, transport-related, thermal, and aging properties of mass concrete are examined with respect to the main processes that can cause it to undergo degradation. Global norms, lab testing methods, and surveillance methods are considered during the comparison with the ones that are used in Turkey. The evaluation demonstrates that one of the major challenges in Turkey is the complexity of incorporating long-term material monitoring records with construction-phase quality assurance procedures: whereas global strategies rely on synchronized lab profiling, non-destructive evaluation, and structural health monitoring. The main contribution of this study is to join global standards, operational oversight methods, and material-level performance measures into a life cycle-oriented evaluation framework that may be used for building concrete dams. This configuration may enhance engineering decision-making about planning for durability, preventing thermal fissures, and monitoring long-term performance. The results may be applied to improve surveillance methods and design methods that are based on durability in current and future concrete dam projects.
