Principles of the performance-based approach for concrete durability
conference paper
In general, design approaches for durability can be divided into prescriptive design
concepts and performance-based design concepts. As discussed in Chap 3, prescriptive
concepts result in material and cover depth specifications from using
factors such as exposure classes and compressive strength. Following this approach,
durability specifications in most existing codes and standards are based primarily on
establishing constraints to the material and mix proportions of the concrete, such as
maximum water binder (w/b) ratios, and total minimum cementitious materials
content, as a function of the severity of the anticipated exposure (e.g. [1] ). Design
for durability includes the correct choice of exposure class and compliance with
material requirements and concrete cover requirements, as well as with placing,
compacting and curing procedures
