Characteristics of Sand of the Oueds in the Region of Oued Righ (Oued N'SA, Oued M'ZAB and Oued Rtem) in the Making of Concrete in the Arid Regions

We usually use, in the making of reinforced concrete, the ordinary sand which is generally extracted from quarry, oueds or from beaches. This material is a necessary element for the concrete, but unfortunately, it is not always available in market and hence makes both rare and expensive despite of its gigantic reserve in the many oueds in the region of oued righ. We have chosen the sand of the oueds as a substitution material in the composition of the concrete taken precisely from Oued N'ssa - Oued M' zab and Oued Rtem. We have opted for an experimental study that deals with the physic-mechanical and chemic characteristics of the sand and its use in the field of concrete construction, as well as the property of this based-sand concrete.
