However, deficiencies remain in the specification of materials used mainly in hydraulic concrete. They are generally related to the specification of aggregates for alkali reactivity and the choice of exposure classes specified in NF EN 206-1. The purpose of this article is to study the incidence of non-compliance with exposure classes in reinforced concrete structures. To carry out this study, surveys were carried out at several sites (districts) in Dakar (Cit¨¦ Avion, Touba Ouakam, Cit¨¦ Asecna, Cit¨¦ Batrain, Cit¨¦ Comico, Cit¨¦ Assembl¨¦e and Terme Sud) in order to collect information on the formulation and implementation methods used. The comparison of the various readings carried out made it possible to deduce conclusions and to give recommendations when using standard NF EN 206-1. %K Common Exposure Classes %K Specific Exposure Classes %K Concrete %K Alkali-Reaction %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=123544
