This European Standard is the first of five parts to assess the thermal compatibility of repair products and systems, including grouts, mortars and concretes and surface protection systems, used for the repair and protection of concrete structures. The method specified in this Part measures the effect of freeze-thaw thermal shock cycling with immersion in saturated de-icing salt solution. The method is suitable for repair products and systems based on CC, PCC and PC binders and for surface protection systems.
