Abstract

In recent year, the use of high performance concrete (HPC) has significantly increased in applications such as prestressed concrete structures, bridges, large-span roof structures, and containers for hazardous fluids or nuclear wastes due to its outstanding structural performance and higher durability. However, its fire resistance performance remains a concern, especially in relation to explosive spalling in a fire. Therefore, it is essential to understand the spalling properties (mechanism, influencing factors, and prevention measures, etc.) of high performance concrete exposed to high temperature, so that the safety of a structural fire design involving HPC can be ensured. This report presents a state-of-the-art review for the prevention measures and explosive spalling of high performance concrete under fire situations.
