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.

Chung et. al., [7] presented the asymptotic homogenization scheme to assess the overall behavior of the piezoelectric composite.
Dunn et. al., [4] gave an explicit form for Eshelby's tensor in terms of integral over a unit spheroid region to determine the coupled electromechanical properties of piezoelectric composites.
Recently, a study by Gandarilla et. al., [8] extended the classical Maxwell micromechanics model considering spheroidal piezoelectric inclusions aligned in parallel but randomly distributed.
The Eshelby tensor components for fiber inclusions in a transversely isotropic matrix are developed by Levin et. al., [9].
