Although the extraction of sea sand is not the only factor responsible for coastal erosion, it is an important phenomenon in the degradation of the coastal environment. For this reason, local authorities have banned the use of sea sand and also operators in the construction sector (Public Works and Water Resources) should use the desert sand that is the only current alternative. Indeed, the alluvial sand usually has better features than the desert sand, but it is not available in sufficient reserves to the needs of the construction sector. The purpose of this study is to characterize (granularity, cleanliness) some quarries of desert sand used in the Dakar region to verify the extent to which they are used in construction and more specifically in hydraulic concrete composition. Furthermore, a method of mixing improved this desert sand with crushed sand 0/3, from the rock crushing mass, is studied below.
Key words: Cleanliness, concrete, fineness, sand, strength, ,
