This work is a part of a general framework aimed at the development of local sands in the Marrakech-Safi region in Morocco. The objective of this work is to experimentally evaluate the influence of Wadi (river) sands and sea sands on the mechanical behavior of concretes.

The results obtained show that the rheological properties of fresh concrete (workability and density) and the mechanical characteristics (compressive and tensile strengths by bending) vary according to the mineralogical, morphology, density and granulometry of the sands used. The analysis of the microstructure shows that the cementitious matrix is very dense for all the concretes tested. In addition, the cement matrix-aggregate adhesion depends on the nature and texture of the sands.

compressed earth blocks, cement, hot ring method, thermal conductivity, temperature, heating power.
