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 specific provision is to be included in specifications for frost resistant aggregates.
