Study of the new type of light magnesium cement foamed material

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 material with excellent properties and the density of 0.15-0.60 g/cm(3) by the process of foaming, compacting, solidifying and lastly gelating as well as foaming 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.
