AB The repeated action of simulated freeze-thaw cycles on Cadalso de los Vidrios Granite, promotesdifferential micro-cracking and loss of cr ystals at the surface and therefore decay. It is possible toestablish a relationship between the evolution of the ultrasound waves velocity (Vp) with the numberof freeze-thaw cycles and the generation of microcracks. Intergranular cracks are formed during thefirst cycles and these propagate towards the inner part of each individual crystals as the freeze-thawcycles advance. Therefore, after 280 freeze-thaw cycles different patterns of microcracking can beobserved depending on the mineralogy. Quartz is the mineral displaying more intense cracking whilebiotite shows less cracking, in part due to its more ductile behaviour. Micro-cracks appear preferentiallyat the surface of the samples with a maximum length and depth of 1 cm. Thus, these samples showedlimited decay highlighting the good performance of Cadalso de los Vidrios granite against freezethaw
