Analysis of alterations presented in a white-concrete façade exposed to a marine environment——A case study in Cádiz (Spain)

<abstract> <p>This study analyses the façades of a white concrete building located in Cádiz (Spain). Numerous sections cladding on have become detached and there are clear signs reinforcement corrosion. For purposes this study, arrangement was evaluated by georadar (GPR). Cylindrical cores measuring 10 cm diameter 15–18 depth were extracted their carbonation front evaluated. Samples characterized physical properties determination; chemical mineralogical analysis chloride penetration profiles.</p> <p>According to results obtained, used can be considered permeable porous (16.5–19.7%). Only two sampling points fulfilled minimum coating requirements for type environmental exposure, accordance with current Spanish legislation. The fronts reached reinforcements, causing depassivation. Depending orientation façade, chlorides from marine spray observed maximum value 0.250% weight cement, without reaching limit states durability.</p> </abstract>
