The sand is an inert element essential in the composition of concrete; its use ensures
granular continuity between the cement and gravel for better cohesion of concrete. This
paper presents the results of a study that investigated the influence of sand quality on the
properties of fresh and hardened self-compacting concrete (SCC). The dune sands are very
fine materials characterized by a high intergranular porosity, high surface area and low
fineness modulus; on the other hand crushed (manufactured) sand has a high rate into thin …
