Abstract

Measurements of the particle size distribution of samples of desert sand from the Great Sand Sea region of Libya are reported. The dune sands proper, being poorly (uniformly) graded, would not normally be regarded as suitable for making concrete, but the sand from the troughs between dunes, being well graded with little or no fines, would be acceptable as fine aggregate for concrete. Some observations are made on the grain morphology and texture of the particles in one sample in relation to its aeolian mode of formation.
