Abstract

Abstract

Tests were conducted on high temperature properties of normal strength high-performance concrete to explore its explosive spalling and mechanical properties at high temperature,to ensure satisfactory fire resistance of concrete structures.The results reveal that both moisture content and density are the two main factors influencing the spalling.When moisture content is over a critical value,the higher the moisture content,the more the spalling frequency.The more dense the concrete,the greater the degree of spalling.Polypropylene fiber at a volume fraction of 0.05 % can prohibit the occurrence of spalling of normal strength high-performance concrete.Moreover,the higher the fiber dosage,the less the thermal damage.Polypropylene fiber has also improvement in residual mechanical properties of concrete subjected to high temperature.
- Normal strength high-performance concrete,
- fire resistance,
