%X From the National Agency for the Organization and Construction of
Infrastructures (ANOCI) program to the Emerging Senegal Plan (PSE),
construction in Senegal has improved considerably. 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.
