This approach is based on the principle that a clear relationship exists between durability expectation and minimum concrete grade, minimum binder content and maximum

Specification of freeze-thaw resistant concrete is exemplified by European practice outlined in the primary specification documents for concrete and aggregates for concrete, EN206-1 and EN 12620 respectively. The former sets out a comprehensive framework for integrating specific concerns in a prescriptive approach to durability. These concerns include provision for freeze-thaw resistance, where applicable. The latter provides guidance to specifiers where
