Abstract
Disclosed is a magnesium-based cementitious material, preparation method and application thereof. The magnesium-based cementitious material, comprising magnesite, sandstone, and water, wherein: the magnesite is provided with CaO, SiO, AlO, FeO, and MgO, a mass percentage of the CaO is less than 5%, a mass percentage of SiOis less than 5%, a mass percentage of AlOis less than 5%, a mass percentage of FeOis less than 7%, a mass percentage of MgO is between 37% and 50%; the sandstone is provided with SiO, CaO, AlO, and FeO, a mass percentage of SiOis greater than 70%. The beneficial effects of this disclosure are: the cementitious material does not contain MgCl, which avoids the reduction of the strength of the cementitious material due to the dissolution of MgClin water; the magnesium-based cementitious material of this disclosure is immiscible with water and has strong water resistance.
