Edificio Bacardí: historia arquitectónica y estado de conservación de un ícono habanero del siglo XX

A study of deterioration was carried out in a building of high heritage value constructed with reinforced concrete. The objective was to study the deterioration of the building resulting from the phenomenon of corrosion in reinforcing steel due to the influence of carbonation, efflorescence and concrete highly contaminated by chloride ions. Different tests such as infrared thermography, compression resistance and determination of the penetration profile of chloride ions, as well as the structural description were used in the study. In this way, results showed that exposure during decades to wetting and drying cycles, in the presence of concrete contaminated by chlorides due to the use of sea sand for the construction of the building, together with poor maintenance actions, lead to advanced deterioration by corrosion. The damage extended to almost the entire elevation of the facades, the reinforced concrete mezzanine slabs and the structure of the lookout tower, with affections due to cracks and detaching of the decorative terracotta. The evaluation of the chloride profiles obtained reflects a high concentration inside the concrete, which increases as you go deeper in the structural element. For depths greater than 6 cm, the free chloride concentration exceeds 0.1% by weight of concrete for all samples drawn. The Bacardí building constitutes the most important example of Art Deco in Cuba and its construction was very complexity, as would be its restoration due to the nature of its elaborated facades.
