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