Durability of High-strength Concrete Made with High Belite Cement

Abstract

A new type of cement, namely the high-belite cement (HBC) has been made in industrial scale in a trial production in China. The kiln feed raw mix proportions are adjusted so as to produce a clinker with the belite phase proportion as high as 60-70%, and alite phase around 15-20%. This paper studied the mechanical and durability properties of high strength concrete made with HBC as the binder. For comparison purpose, concrete with same strength made with ordinary Portland cement (OPC) was also cast and tested. Results show that the concrete made with HBC has comparable strength and durability properties with that made with OPC. 12
