Comparison Behaviour of Dune Sand with Reference Sands Using Direct Shear Tests

Abstract

The rapid increase in sand consumption, in the road sector and in building construction, is such that serious supply problems are currently posed in some countries. These problems are all the more crucial as the dune sands (due to the quality and abundance in arid regions and the other desert areas). The main objective of this study is to determine the geotechnical properties of dune sand as local materials to reduce the price of building materials. Different dune sand samples were used and their physical, mechanical and chemical properties were also examined. The properties of the dune sand were compared with standard sands to show its ability and advantage. The results show that dune sand has geotechnical and mineralogical characteristics closest to Standard sand. Results can be used to improve the geotechnical properties of dune sand as building materials.
