Why is desert sand not used for construction? I Geotechnical Engineering I TGC Episode 23

Many countries rely on imports of natural construction materials as they lack resources of their own. Perhaps surprisingly, this includes countries with seemingly limitless supplies of sand, such as the United Arab Emirates (UAE). The UAE was, in fact, the world’s fifth largest importer of sand in 2018 and imported US$292m of sand between 2015 and 2019, according to the International Trade Centre. 

This is because desert sand is unsuitable for construction, as it is very fine grained and the grains are round and smooth, giving it low strength. Desert sand also has a high alkali content, as it contains salt deposits left behind from evapotranspiration.
