The properties of concrete made with fine dune sand ...

This paper presents the results of a study that investigated the properties of concrete made with dune sand. Different control concrete mixtures using ordinary Portland cement (OPC) with a minimum design compressive strength of 40 N/mm 2 were prepared. The amount of fine aggregates constituted about 36% by weight of all the aggregates.
