DEVELOPMENT OF BELITE BASED CEMENTS IN CHINA

摘要

Great progress has been made recently in China concerning the research and development of belite based cements. This paper is a brief review of different system of belite cements. Some typical properties of these cements especially high belite Portland cement (HBC) are introduced. The study indicates that HBC, due to its low calcium mineral design, possesses not only lower clinkering temperature and less CO_2, SO_2 and NO_X emission in its production, but also the characteristics of lower-heat evolution, higher late strength and excellent resistance to sulfate, etc.
