This standard is the fourth in a series of five parts to assess the thermal compatibility of repair products and systems, comprising 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 dry thermal cycling without exposure to de-icing salt, upon the repair product or system. The method is suitable for repair products and systems based on CC, PCC and PC binders and for surface protection systems.
