Study of the Use of Dredged Sand as An Alternative to Beach Sand and Coastal Dunes for Coastal Preservation

The need for construction sand needs to increase due the in population. use of dunes and coastal disfigures shorelines consequences are alarming. It is therefore necessary consider replacing these resources with other more ecological ones. Hence, it purpose this article. In paper, we study correct formulation concrete using dredged sand, respecting standards, analyze impact new material on physical mechanical characteristics concrete. This article aims evaluate effects 9 formulations, used as substitutes ordinary physico-chemical properties. experimental results have shown that affects properties concrete, but standards force. mode incorporation also has an environmental advantage over substitution reduces disfigurement coasts. paper studies dredge sands from two regions namely Azemour Mehdia. dredging partially or totally replaces sand. Subsequently, was test several formulations different cement dosages before arriving at which exposed study. fresh state (consistency test) hardened (mechanical resistance) possible, consequently can concretes mortars. true shows a reduction resistance compared control reductions still remain accordance Moroccan regulatory specifications.
