Abstract：Magnesium silicate-based cementitious materials are generally obtained by mixing activated magnesium oxide,admix-ture and siliceous raw materials in certain propertion,which have excellent characteristics such as low carbon emissions,light weight,high strength,and better thermal insulation performance,and have received extensive attention from scholars at home and abroad.The research progress of magnesium silicate-based cementitious materials is mainly summarized from the aspects of raw ma-terial ratio,hydration mechanism,and influencing factors of properties.The properties of magnesium silicate based cementitious mate-rials is mainly affected by MgO activity,curing temperature,Mg/Si ratio,and the dosage of additives and admixtures.The MgO ac-tivity and Mg/Si ratio have a significant impact on the reaction products of the system,and the curing temperature plays a control-ling role in the reaction process.This article provides an overview of the current problems in magnesium silicate-based cementi-tious materials and proposes feasible improvement measures.
