Study of formation of magnesium oxychloride phase MOC-518 by isothermal calorimetry
Original language description
In this paper, the 5Mg(OH)2.MgCl2.8H2O also known as magnesium oxychloride cement phase 5 (MOC-518) was prepared from pure MgO and MgCl2????????????2O. Before the synthesis, pure MgO was characterized by X-ray diffraction, X-ray fluorescence, sorption analyzer (BET) and laser diffraction. The kinetics of MOC-518 formation was analyzed by X-ray diffraction and by means of isothermal calorimetry. When the reaction was over, the sample was characterized in detail by scanning electron microscopy and energy dispersive spectroscopy. In addition, mechanical properties in time relation such as compressive and flexural strength, were determined. Results confirmed that the particle size as well as surface area of starting MgO significantly influence the phase formation rate of MOC-518.
