A Climate Change Impacts on Structural Durability of Concrete

Abstract

Concrete is widely used in engineering constructions such as buildings, bridges, and other infrastructures due to its strength, durability, and sustainability. Extreme environmental factors like changing temperatures, chloride ingress, and carbonation can significantly affect its performance in the long-run. This study observed the global warming trends from the Intergovernmental Panel on Climate Change (IPCC). Thus, the purpose of this study is to determine how climate change affects concrete's structural durability. We have conducted few concrete cubes experiment into the influence of elevated temperature of above 25˚C exposed by concrete experienced strength loss due to altered hydration pattern. Similarly, the experiment found that chloride concentration of up to 0.5% and carbonation depth exceeding 20mm in concrete cube. Numerous case studies were examined and collected from different locations throughout the world to provide insight into how climate change affects the longevity of concrete. In respect to this, a summary of empirical evidence of degradation is presented, which suggests additional adaptation and mitigation options. However, this paper provided a full grasp of the planning and maintenance of structural durability for civil infrastructure in a created environment, highlighting the difficulties and implementation in earlier research work.
