Optimization of magnesium oxychloride cement formation using experimental design methodology
Written by sctunisie no commentsIn this work, the experimental design methodology is applied to optimize the condition of formation of Magnesium chloride cement. A four factors factorial design to model and to optimize the operating parameters that govern the formation was used. The studied factors were mass ratio of MgCl2.6H2O/MgO, mixing time and stirring speed. Considered responses are compressive strength and setting time. The optimum operating conditions were quite efficient to have a good compressive strength and suitable setting time. The phases compositions of magnesium oxy- chloride cement were evaluated by X-ray diffraction, the morphological properties were examined by SEM and their thermal behaviour was analyzed by DTA/TGA. The presence of phase 5 confirms the good compressive strength of magnesium oxychloride cement.
