Abstract

This study is an experiment for reducing effect of explosive spalling by fiber addition ratio and kinds of fiber at high performance concrete. So, high strength concrete were made addition to PVA and PP fiber as diameter of 34, 100 $\mu$m and 40 $\mu$m by fiber addition ratio as 0.05, 0.1, 0.3$\%$. After those were heated respectively for 30 in accordance with Standard Time-Temperature Curve. And then conditions of explosive spalling were divided into four grades, and characters of explosive spalling were investigated.
