A new type of light magnesium cement foamed material

By introducing an inorganic foamer, a new type of magnesium cement with high strength and water resistance is applied as the base material to prepare successfully a series of light magnesium cement foamed materials with excellent properties and a density of 0.15–0.60 g/cm3 by the process of foaming, compacting, solidifying and lastly gelating as well as forming the closed porosity materials. After measuring systematically the properties of light magnesium cement foamed materials, the phase compositions are studied by means of the XRD patterns. The results are discussed and concluded.
