Dolomite is a natural carbonate rock,which is abundantly available,widespread and inexpensive.The efficient utilization of dolomite powder as a new supplementary cementitious material (SCM) can meet the needs for cement-based materials with low embodied carbon and low cost,and improve the performance of cement-based materials at some degree,which has significant technical and economic benefits.Therefore,the effects of dolomite powder on the properties of cement-based materials are summarized in terms of workability,mechanical property and durability in this paper by reviewing the latest research results of dolomite powder applied in cement-based materials,and the chemical behavior of dolomite powders in cement-based materials is also analyzed.The dolomite powder as a new SCM applied in cement-based materials can improve workability and volume stability,and react with cement to form calcium carbo aluminate to promote the strength development.Additionally,Mg-Al hydrotalcite can be formed in the cement pastes containing dolomite powder at elevated temperature,which can improve further the strength and durability of cement-based materials,facilitating the application of dolomite powder in cement-based materials.The current study about the application of dolomite powder in cement-based materials is insufficiency,further research and improvement are still needed in the future in terms of the reaction mechanism of dolomite powder and its influence mechanism on properties of cement-based materials.
