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% ...

Recently, nanotechnology has attracted a considerable scientific interest due the potential new uses of non-particles, which can improve the properties of cement mortars or concretes, such as Nanosilica. Nanoparticles, like those of nanosilica, have been shown to have unique physical and chemical properties different from those of conventional cement additions. Nanosilica was used either to replace part of the cements or as an addition to improve the performance of the cement such as accelerating the hydration of ...
