This study aims to improve the stability of alkali-activated products, such as powdered volcanic scoria and metakaolin, by thermal treatment in addition to their partial replacement with aluminium oxy-hydroxide. To this effect, mixtures obtained from

Two volcanic ashes with differences in mass percentages of oxides in chemical composition of amorphous phase were activated by phosphoric acid (P2O5 / H2O molar ratios between 0.04 and 0.15). Amorphous phase was mainly composed of SiO2, Al2O3, CaO, M

Red ceramics were produced at 750°C by mixing reddish yellow kaolinite clay from Marom (West Region of Cameroon) with waste glass (percentage ranging between 0 and 15% mass). Depending on the nature of the materials, kaolinite clay, waste glass and
