“…C when sea level rise is considered, the distance from the coastline to the structure decreases, leading to increased surface chloride concentration. According to Bruun's (Pijaudier-Cabot et al, 2004) equation, when sea level rise is S(t), and the average slope along the overall coastline is i d (i d = 0.5-1.5%), then the distance from the coastline to the structure will be reduced to:…”

“…Global studies have considered the negative impact of climate change on new and existing infrastructure (Andrade and Castillo, 2003;Saha and Eckelman, 2014;Stewart et al, 2011Stewart et al, , 2012Talukdar and Banthia, 2013). Increasing temperature and rising seawater levels are both climate change-related phenomena that can impact the durability of concrete structures (Medeiros-Junior, 2018;Pijaudier-Cabot et al, 2004).…”

“…According to ACI 365 (Clifton, 2000;L'Hostis et al, 2011;Pijaudier-Cabot et al, 2004), service life consists of the corrosion initiation time and the corrosion propagation time. The corrosion initiation time is defined as the time it takes the chloride content at the steel rebar surface to reach critical level.…”

Introduction: Climate change (temperature rise and sea level rise) has a considerable influence on the behavior of concrete structures over time. All concrete degradation processes are connected to climate variables and the effects of climate change. The RCP8.5 (Representative Concentration Pathway) scenario, which is part of the report on climate change and level rise scenarios for Vietnam, predicts that the beginning of the 21st century will see an average annual increase in temperature between 0.8 and 1.1°C. In the mid-21st century, the temperature will likely increase by 1.8–2.3°C, with the temperature in the north likely increasing by 2.0–2.3°C and in the south by 1.8–1.9°C. In marine environments, the degradation of concrete structures can occur rapidly due to chloride-induced reinforcement corrosion. Furthermore, sea level rise is going to reduce the distance from the coastline to the structures and lead to increased surface chloride concentration. Methods: The evaluation of chloride penetration was based on the ASTM C1202 test (ASTM, 2012). The cylinder specimens (d = 100 mm, h = 200 mm) used for a rapid chloride penetration test (RCPT) were immersed in water for 28 days in a water-curing tank. Results: This study proposes a predictive model for analyzing the impact of climate change on the service life of concrete structures on Vietnam’s North Central Coast. The corrosion initiation time decreases by 16.5% when the effects of both temperature rise and sea level rise are taken into consideration. When only temperature rise is taken into consideration, the rate of reduction is approximately 9.0%. These results reaffirm that climate change has a significant effect on the corrosion initiation time of concrete structures located in a marine environment.

“…Additionally, the porosity of concrete may increase over time, making it more susceptible to moisture penetration and chemical attacks. These changes in mechanical and physical properties highlight the importance of proactive maintenance and rehabilitation efforts to ensure the long-term performance of concrete structures [59][60][61].…”

This article addresses the often overlooked but critical long-term factors of creep, shrinkage, ageing and corrosion in civil engineering structures. The paper emphasizes their substantial impact on structural mechanical resistance and safety, drawing attention to key examples like the Civic Tower in Pavia, the Koror-Babeldaob Bridge and dams in the USA. By exploring the challenges faced in modern engineering, the article sheds light on the need to consider these effects. Various models for predicting creep and shrinkage in concrete structures are introduced as potential solutions. In conclusion, the paper highlights the necessity for engineers to navigate the intricacies of material behaviour for successful construction amidst evolving challenges.
