The research related to mineral and rock durability consists in studying the relationship between the mineralogical and textural properties of rocks and their mid to long-term behavior in a construction context (cutslopes, embankments, aggregates, road pavements...). Those relationships are not evident, and the degradation processes occur in any type of geological formations, which involves a variety of lithologies and textures of a complexity that is not reflected in the simple terms used to designate them (i.e. claystones, siltstones, shales, basalts or granites). The approach usually involves 3 aspects: a) field work, in order to characterize the degree of durability and collect undisturbed samples; b) lab work, which includes mineralogical and petrographical studies through optical microscopes, X-ray diffraction, X- ray fluorescence, porosity determination... which are faced with durability analysis (slake durability test, micro-deval); c) office work, to interpret data and find the key mineralogical factors that influence rock durability, and correlate them with their physical properties.
