Laboratory simulations of salt weathering (using sodium sulphate) and freeze–thaw attack (using an Icelandic Cycle) on 19 different limestones indicate that the rocks do not respond in an identical way to the two processes. Resistance to salt is a poor predictor of resistance to frost. Moreover, Young's modulus of elasticity, which was determined by the Grindosonic method, appears not in itself to be a reliable indicator of resistance to frost attack.
