Abstract

In order to valorize our natural resources especially dune sand, the physical and mechanical properties of adhesive mortars based on local mineral additions, have been studied in this present work. The experimental study was carried out on various adhesive mortars made with different contents of dune sand by partial substitution of cement. Adhesive mortars were made from Portland cement (PC; at 35%, 30% and 25%wt), Dune Sand (DS; at 60%, 65% and 75%wt), fillers and redispersible polymer powder (RDP; at 0.6%, 1.0% and 1.4%wt.). The physical (Slump test, normal consistency and bulk density) and mechanical and (initial adhesion, adhesion after immersion in water and adhesion after heat treatment) properties of elaborated adhesive mortars were determined and compared to commercial adhesive mortars.
