In developing sector like construction industry, different materials are used for the infrastructure development. For example, Concrete is the most widely used building material in the world because of its strength, durability and it is favourably used in nearly all type of construction. Reinforced concrete structures can deteriorate in a rapid rate due to exposure to aggressive environment, issues related to poor workmanship, limited availability of good quality materials and lack of awareness on good construction practices. This is exacerbated by climate change and associated increase in deterioration mechanisms, which is not accounted in the design of reinforced concrete structures. The World Bank climate change impact study suggests that under 4°C warming, the coastal regions are projected to shift to new, high-temperature climatic regimes, sea-level rise and storm surges that will lead to salt water intrusion in the coastal areas and increased carbon dioxide in the atmosphere and will collectively have a damaging effect on the performance of concrete structures. To construct durable and resilient concrete structures which are capable of withstanding the aggressive environment for the intended design life, there is a need to study the local factors that influence concrete durability. The major factors that contribute to premature deterioration of concrete structures in aggressive environments and factors related to the development of cost-effective concrete mix design to enhance the durability of future structures and recommendations on improvements in construction practice and workmanship are necessary to improve the service life of structures.
Considering all these, to develop a sustainable, climate resilient structures with improved service life, there is a great need to the academicians, practitioners and technologists to consider major factors that contribute to premature deterioration of concrete structures in aggressive environments and factors related to the development of cost effective concrete mix design to enhance the durability of future structures with recommendations on improvements in construction practice and workmanship.
