Abstract
This thesis presents the results of an experimental study on the influence of
partial substitution of dune sand with recycled sand from clinker and faience
waste, as well as the incorporation of Dramix-type metallic fibers, on the
behavior of sand concrete in both fresh and hardened states. The materials used
originate from Eastern Algeria. Evaluated properties include workability,
density, air entrainment, compressive strength, flexural and splitting tensile
strengths, hardness, and chemical resistance to acid attacks. These properties
were compared to those of sand concrete without fibers. The results show a
significant improvement in workability, air entrainment, compressive, flexural,
and splitting tensile strengths. However, there are higher mass losses in fiberreinforced
concretes compared to the control concrete during immersion in
H2SO4 acid.
