Abstract: The production of traditional Portland cement is facing great challenge because of consuming a large amount of resources and energy,as well as emitting of CO2,therefore,it is urgent to produce low-carbon cements.In order to improve the properties of low-carbon cements with high amount of belite,the article analyzed the principle of belite activation and compared the advantages and disadvantages of three methods.The results show that chemical doping is the most effective method and the effect of B2O3 doping on belite activation is quite remarkable.It is also pointed out that the introduction of calcium sulfosilicate not only play a positive role in improving cement performance,but also have important practical significance for the development of low-carbon cement.

Key words: low carbon cement;belite activation;chemical doping;calcium sulfosilicate
