These results are in agreement with those reported by Achoura et al. [34]. 2 HCl + Ca(OH)2 → CaCl2.2H2O (hydrate calcium chloride) (2) 2 CH3COOH + Ca(OH)2 → Ca(CH3COO)2.2H2O (hydrate calcium acetate) (3) The chemical resistance of materials is more or less affected by the concentration and the nature of acids in the order with the most aggressive as given below: HCl > H2SO4 > CH3COOH.
These results are in agreement with those reported by Rossignolo et al. [32].
These results are in agreement with those reported by Benosman et al [27].

However, Kute et al. [4] have studied clay bricks made from clay and fly ash.
Oti et al. [8] studied the physical and mechanical properties of lime-stabilized green clay bricks.
Millogo et al. [10] presented a study of clay blocks reinforced with Hibiscus cannabinus fibers.
Mounir et al. [12] studied a clay-cork composite material.
Mathioro Fall. et al. [17] studied bricks made from local materials such as clay, laterite and sand.

The strain response of the sample, exemplified by Eq. (5) in the case of a linear system, includes the elastic component, related to the elastic strain of the lattice el ε and anelastic component anε .
Second, the concentration of point defects, accommodating for nonstoichiometry of the alloys increases with deviation from the stoichiometric composition both for Al-rich and Al-depleted alloys.
This feature is exemplified in Fig. 7 for Cu-Al and Cu-Al-Be alloys and reflects an unusual non-additive coupling of linear and non-linear damping components, when the Eq. (7) breaks.
Cu-Al-Ni alloys with γ'-martensite exhibit a twin relaxation peak as observed by K.

Swaine et al. [5] list As, Cd, Cr, Hg, Pb and Se as elements of greatest environmental concern; B, Cl, F, Mn, Mo, Ni, Be, Cu, P, Th, U, V, Zn of moderate concern; and Ba, Co, I, Ra, Sb, Sn and Tl of minor concern.
Elemental analysis of all samples was also performed by Elemental Analyzer (Vario EL Ⅲ) Department of coal and CBM engineering, Faculty of Earth Resources, China University of Geosciences.

Attending to the Romeiro Filho et al. [5] observation, for which "each company has its own culture and each project has its own characteristics", the proposed model is used to organize the processes of design, management and implementation of all diversity of R&D projects in the electricity sector, guiding teams and managers in an efficient and strong process directed to the guidelines of the R&D Program of Brazilian Electricity Sector process, although linked to the main processes of product development.

Hansen et al. proposed the method that combines coplanar and nearly coplanar polygons in to larger polygon which can be re-triangulated in to fewer simpler polygons [8].
Kalvin et al. have presented the simplification method called a "superfaces" [9].
Gardland et al. have presented the method which can be applied not only to the surface simplification tasks, but also for the collision and intersection detection [10].
Another different method for the representation of highly detailed objects is presented by Aaron Lee et al.
