Etude Experimentale D'un Beton Avec Le Sable De Dune

Résumé: All studies led in the setting of constructions in reinforced concrete and on the quality of the concrete in general are made to basis of sand normalized of career, owed or beach, to the free state. It is an indispensable material; unfortunately, its availability makes it very rare and expensive. However seen the availability of the dune sand to the natural state in the south in very important quantity and has low price we decided to study the different features of this material for its use in the concrete. Seen its very fine granulométrie we will suggest that the survey is made with a mixture of dune sand more another normalized sand. To permit a good compactness of the concrete, the composition of this one will be studies with a granulométrie of two types of gravel (3/8) and (8/15). The objective of the survey will consist in valorizing this sand of dune in the composition of the concrete that will permit to reduce costs of the meter cubes of the concrete and the possible improvement of theirs mechanical qualities. The composition of the concrete will be studied according to different sand proportion next one used. - 100% sand of dune - 75% sand of dune + 25% sand of curry - 50% sand of dune + 50% sand of curry - 25% sand of dune + 75% sand of curry - 100% sand of curry
