In this paper, the strengths under different curing conditions, heat evolution as well as resistance to sulphate have been discussed for High Belite Cement (HBC) in comparison with Ordinary Portland cement (OPC). In addition, R&D of high-performance concrete prepared by HBC as the main component of cementitious material with strength grades C50∼C80 (equivalent to minimum requirement for 28-day compressive strength 50MPa∼80MPa) was conducted. And the workability, physical mechanical properties, durability of HBC concrete have been discussed as compared to OPC concrete. The research results indicate that HBC possesses higher late strength after 28-day age though its early strength is relatively lower, lower hydration heat evolution and excellent resistance to sulphate. Moreover, HBC concrete exhibits excellent workability, physical mechanical properties and durability.
