Abstract

Recently, extreme climate change has been occurring globally not only in the simple form of temperature increases but also in a wide range of extreme climatic events, such as abnormal drought conditions and frequent typhoons. Among these various events, the greatest problem is found in global warming. The earth`s temperature has risen since the period of rapid industrial growth in the 1970s, and global warming occurs at the local level of regions and cities as well as the national level. The greenhouse gases that influence global warming include various types of chemical components, such as carbon dioxide (CO2), perfluorocarbons (PFCs), nitrous oxide (N2O), and methane (CH4). In addition, climate change is extending the construction period of concrete structures. Whereby increasing related economic losses. Pushing through construction projects without considering climate change is leading to concrete quality deterioration, causing poor constructions and consequently resulting in humans casualties and property damage. In particular, atmospheric CO2 generates calcium carbonate by reacting with concrete hydration products. This result is reinforcing bar corrosion and concrete durability reduction due to lowered alkalinity. Therefore, in this study, concrete durability performance with respect to carbonation resistance from curing conditions change due to wind speed and sunlight exposure time is evaluated. Based on concrete carbonation resistance data obtained using curing conditions of various wind speed and sunlight exposure time, performance based evaluation (PBE) is performed using the satisfaction curve (SC) developed from the carbonation resistance test results. Using the developed PBE of concrete performance, future concrete performance is predicted based on future climate scenario. Also, the concrete mix design solutions to the concrete performance degradation due to climate change effect is proposed.
