For instance, Lila et al. [5] used olive kernel-derived products as an additive in cement manufacturing, while in the work of Farag et al. [6] olive kernels were mixed with a polyester resin to produce particle boards for interior design.
Ferreiro-Cabello et al. [8] made an attempt to replace 100% of sand with olive kernels, however authors experienced difficulties with substitutions above 30% and therefore the mechanical properties of mortars with relatively low inclusion of olive kernels were investigated as a function of cement type and curing time.
In the works of Boukhelkhal et al. [9] and Cheboub et al. [10] self-compacting mortars were produced with a substitution up to 50% and 100% of sand by olive kernel, respectively, and mechanical properties as well as moisture-related and thermal properties were investigated.
Among the examples found in the literature, only Cheobub et al. [10] explored the properties of 100% olive kernel mortars, while other researchers only focused on partial substitutions of the aggregate.

Intermetallic phases of Ti-Al system have high mechanical strength, hardness; wear and corrosion resistance [5–6].
It was calculated by the formula where contributions of strengthening from internal stresses (shear and moment stresses) are added quadratically, the other contributions are summed additively [13]: , (1) where Dsfr is friction stress of dislocations in crystal lattice of a-Ti; Dssol is strengthening of UFG-Ti solid solution with atoms of alloying elements (Al, С, О); DsF is strengthening of “forest” dislocations which are intersecting gliding dislocations (internal shear stresses); Δσl is strengthening with long-range stress fields, formed by excess dislocation density (internal moment stresses); DsOr is material strengthening with non-coherent particles when they are by-passed by dislocations according to Orowan mechanism; Dsg is strengthening due to grain boundaries.

Moulin et al. [3] report that conventional lightweight cementing systems develop low compressive resistance, high porosity and permeability, and such characteristics limit its application.
El-Hassan and Abdelrahman [6] indicate that the granular materials optimization not only benefit the performance of the fluid properties but also improve mechanical properties of the set cement.
According to Iverson et al. [7], due to the position of the cement slurry between the casing and the formation, the understanding of its mechanical behavior is crucial to know the slurry cement behavior interaction throughout the lifespan of the well.
