Abstract


High Alumina Cement (HAC) concrete was used in Spainfrom 1950 to 1970 in the production of prefabricated prestressed joist for floor slab construction, using cement produced by Cementos Molinsfrom 1928 under licence from Lafarge (France). Recent collapses have led to new investigations on buildings under suspicion of having HAC concrete joists. The number of dwelling under suspicion has been evaluated elsewhere in 100,000 in Barcelona and 50,000 in Madrid, these ciphers are, in the authors' opinion, exaggerated. This paper explains INTEMAC’s experiences and methodology for the in-situ inspection, sampling and testing, leading to the corresponding diagnosis and, in some cases a proposal for repair and maintenance practices.
