State of the art review on prescriptive & performance based approaches for concrete durability

Abstract

Durability has become one of the most important requirements for the concrete structures across the globe. A durable concrete not only leads to the sustainability but serve for longer period without much repair and maintenances for the concrete members. The Concrete in various exposures such as mild, moderate, severe, very severe and extreme conditions was studied by researchers but no significance attention is given for the performance of the concrete in service. In the last few decades, many researchers investigated the causes of structures deterioration and suggested various solutions to tackle the durability issues which are mainly adopting of performance-based specifications rather than prescriptive. In this paper, the previous findings on concrete durability are reviewed. The studies on the durability problems are highlighted along with prescriptive and performance-based approaches and test methods. The effects on service life of the structures along with the solution are reviewed.
