Shrinkage, cracking, self-healing and corrosion in blended cement concrete

点击翻译按钮获取中文摘要

This project aims to investigate the effects of binder quantity and composition on early-age cracking in Australian concretes caused by restrained shrinkage, the subsequent self-healing capability of the cracks, and the possibility of detrimental early chloride induced steel reinforcement corrosion, particularly in marine locations. This project will focus on concrete mix designs and the blends of cement, fly-ash and blast furnace slag that are prescribed in the revised version of the concrete bridge standard for the most severe exposure. This project will lead to a significant improvement in the serviceability and durability of concrete structures in severe environments.
