Constructive Aspects of the Artificial Stone Veneer (arcosita "Butsems") of the South Fa?ade of the Spanish Senate Palace

摘要

The South fa?ade of the Senate of Spain (Marina Square, Madrid) has undergone transformations since it was the old Convent-College of the Augustinians (1581-1601). According to photographical and historical documentation, by 1951 the coating was fully repaired and all its compositional and ornamental elements were dismantled. The reconstruction was carried out using cladding with an artificial stone (polished “arcosita Butsems”) made with a low content of portlandite, according to the XRD and FTIR tests performed. This paper covers the taking of samples, the testing and analysis of the materials, and a brief description of the pathological processes suffered as a result of the manufacture and installation of the cladding.
