Abstract: The main objective of this study is to deepen the characterization studies already led on concretes in previous works. Indeed, it depends in examining the effect of the sand type on the main properties of concrete. The particularly insist on the determination of the strength characteristics of this material. To carry out this study, two different types of sand have been used: Dune Sand (DS), Sea Sand (SS). These sands differ in mineralogical nature, grain shape, angularity, particle size, proportion of fine elements, etc. The obtained results show that the particle size distribution of sand has marked its influence in all the studied properties of concrete, since, the sea sand having the highest diameter and the best particle size distribution has given the best properties. The grain shape, the angularity and the nature of sand have also marked their influence: thanks to its angularity, sea sand yielded better results compared to dune sands which. Finally, it should further be noted that the dune sand concrete presents values of compressive strength slightly lower than those of sea sand concrete but almost comparable.
