“…KO1 specimens stabilised at 30% feldspars and fired at 1100˚C show the highest resistance (23.84 MPa). This resistance is close to that of the concrete (25 MPa) [25]- [28]. Figure 19 and Figure 20 present the compression test at 1000˚C and 1100˚C respectively.…”

“…After drying, the raw product is subjected to a heat treatment called bisque carried out at a temperature between 900˚C and 1230˚C. Deformation and removal of the shard during this stage are limited because of the very nature of refractory raw materials [25]- [28].…”

“…These are spherical waves interfering with each other, that is to say, their intensity is increasing in certain directions of space and cancels in other directions each. It is this constructive and destructive interference between the spherical waves that are at the origin of the phenomenon of X-ray diffraction by the crystal [25]- [28] [38].…”

As a part of the framework of the development of ceramic products, scientific research continues this idea that clays are essential vehicles for local development in Africa; and therefore they deserve to be made profitable. This scientific work has the advantage of providing a solution to the housing of the Sahel area. On the other hand, this study can effectively serve as the basis of data in the formulation of ceramics from clay Maroua, in the region of the Far North Cameroon, for a large-scale industrial operation. Thus, two samples of materials respectively KO1 and IP2 have been the subject of a preliminary chemical and mineralogical size rheological study. Once formed, the tubes containing the KO1 and PI2 materials have undergone heat treatment at successive temperatures of 900˚C, 1000˚C and 1100˚C. The baked products obtained have also been the subject of a study of resonance, coloring density, loss on ignition, water absorption, linear shrinkage, porosity and mechanical compression.

Several geopolymer-based materials were produced and characterized by mixing metakaolin, a commercial sodium silicate solution, a sodium hydroxide solution, and a loose waste olivine sand deriving from a metallurgical process devoted to the production of a high manganese steel. Olivine sand was added either in the as-received form or after a thermal treatment at 900 °C. Hardened materials containing different amounts of olivine sand were characterized and their behavior was compared to that of a blank geopolymeric matrix. Materials were examined by X-ray diffraction, Fourier Transform Infrared Radiation, and optical and scanning electron microscope investigation; mechanical compressive strength was discussed taking into account water absorption and microstructure. It has been observed that all compositions containing the as-received olivine sands badly perform, whereas those prepared using thermally treated olivine have higher compressive strength than the reference blank composition. In particular, samples with composition containing 100 g of metakaolin and 75 g of olivine displayed the best overall behavior. Graphical Abstract
