AB  - 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.
