“…Crack initiation and propagation for different global warming scenarios were calculated. Stewart et al [16,17] proposed climate change adaptation strategies for corrosion control of concrete. That study revealed that increasing cover thickness, improving the quality of concrete, and using coatings and barriers can ameliorate the effects of climate change.…”

“…However, the previous studies [12][13][14][15][16][17] mainly focused on the effect of global warming on chloride ingress. The effect of sea level rise on chloride ingress was not considered in the studies [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. With the rise in sea level, the distance between the coast and structure decreases, the surface chloride concentration increases, and, consequently, the rate of chloride ingress and the rate of corrosion both increase as well.…”

“…Since the rise in sea level was not taken into account, previous models [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] underestimate the rates of chloride ingress and steel corrosion and overestimate the service life of coastal concrete. To address the weak points of previous studies [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], this study considers the effect of sea level rise on service life.…”

Global warming will increase the rate of chloride ingress and the rate of steel corrosion of concrete structures. Furthermore, in coastal (atmospheric marine) zones, sea level rise will reduce the distance of concrete structures from the coast and increase the surface chloride content. This study proposes a probabilistic model for analyzing the effects of global warming and sea level rise on the service life of coastal concrete structures. First, in the corrosion initiation stage, an improved chloride diffusion model is proposed to determine chloride concentration. The Monte Carlo method is employed to calculate the service life in the corrosion initiation stage; Second, in the corrosion propagation stage, a numerical model is proposed to calculate the rate of corrosion, probability of corrosion cracking, and service life. Third, overall service life is determined as the sum of service life in the corrosion initiation and corrosion propagation stages. After considering the impacts of global warming and sea level rise, the analysis results show that for concrete structures having a service life of 50 years, the service life decreases by about 5%.

“…Finally, when there is a possibility of moss, ivy or fungi to have an impact on the structure, among other similar materials, this is a biological factor [6]. Many of these factors may overlap or have an effect on one another, as well [7]. This is due to the fact that concrete is extremely porous and therefore when there is a corrosive or physical effect on the material it is likely to face structural failure [7].…”

“…The use of steel reinforcement also has an impact on the way that concrete degrades. Corrosion may be able to decrease the structural capacity of the concrete as a whole through decreasing the cross sectional area of steel reinforcement, which is at an increased risk when it comes to managing the greater loads that are expected in pre-stressed concrete structures [7]. In other words, when it comes to the evaluation of the other.…”

Abstract. Concrete degradation is arguably the main restriction on longevity of service life of buildings and infrastructure, most developed economies spend more on rehabilitation of existing structures than on new one. Concrete can be damaged by a range of chemical , physical and biological cause that include; fire, sea water, aggressive environment, corrosion of reinforcement, impact, bacterial attach to name a few. There is a continuing argument about the main cause of the premature deterioration of structures containing reinforced concrete, these range from inadequate specification, poor design and detailing, poor workmanship and aggressive environment. By far the biggest cause of deterioration is the corrosion of the steel reinforcement, with its expansive byproducts that result in the cracking and spilling of concrete and can ultimately cause total service life failure of the structure if not checked and remedied. Maintenance engineers face an ever ending problem of when is the optimum time to intervene and rehabilitate a deteriorated structural element or whole structure. Budget restrictions and need to optimize the maintenance cycle. The paper will report on a large database of deterioration records of concrete bridges covering a period of over 60 years and include data from over 400 bridge structures. Statistical analysis were used to estimate the deterioration rates of various reinforced concrete defects in a rage of structural elements and bridge types and to arrive a mean service life of reinforced concrete defects in a rage of structural elements and bridge types and to arrive a mean service life of the structure, such service life data can then be used by the maintenance manager to budget and prioritize his maintenance work.

The durability of reinforced concrete bridges is crucial for ensuring their long‐term functionality and safety. Among the various deterioration mechanisms, carbonation and chlorides are the most significant and widespread problems affecting these structures. This paper aims to assess the durability condition of the historical Colombian Bridge “Laureano Gómez”, which has been in service for over 40 years. The condition assessment involved measurements of the concrete cover, carbonation depths, concrete resistivity, compressive strength, crack survey, and visual inspection of the steel surface. Estimating the remaining service life showed that the stay elements are the most prone to steel depassivation due to carbonation, primarily due to low concrete cover and exposure conditions. The insights from this study could provide valuable information for the durability prognosis of the new bridge built next to it.
