Geotechnical Behavior of Stabilized Dunes Sand by Cement
Journal of Civil Engineering and Construction, 2021 The dunes sand is wide spread with huge quantities all over the world especially in desert areas near roads. The objective of the current paper is to use dunes sand as a foundation soil under structures instead of utilizing expensive replacement with structural fills.

DUNE STABILIZATION WITH A SAND/GEL COMPOSITE SYSTEM
Coastal Engineering Proceedings, 1988 The effectiveness of a novel sand/gel composite system for the temporary stabilization of coastal dunes was demonstrated in wavetank and field testing. The composite consists of 97% beach sand and water, with a few percent of a biodegradable aqueous polymeric gel made from nontoxic ingredients. The gel binds the sand into a firm but resilient composite

Characterization of Sand Dunes to Detect the Sand Source and their Stabilization, Abardej, Iran [PDF]
International Journal of Geography and Geology, 2016 A dune field was investigated to detect dunes morphology, physiochemical and mineralogical specifications in Abardej region in the southeast of Tehran, Iran. The border of dunes was determined using aerial photographs and field observations, and then the various shapes of dunes were found.

Stabilization of Baiji Sand Dunes by Petroleum Residues
IOP Conference Series: Materials Science and Engineering, 2020 Abstract This research is concerned with the use of petroleum residues to stabilize Baiji sand dunes. The purpose of this research is to study the stabilizing effect of these residues irrespective of their possible toxicity to plant and environment. Two petroleum mixtures were prepared in different mulching rates to test their efficiency
