Abstract High Strength Concrete (HSC) has weakness that in a fire, it is spalled and brittles. The phenomenon of spalling is made by water vapor's being confined in watertight concrete. This study is aimed to evaluate explosive spalling properties of high strength concrete with □100×100×200 mm specimen and □400×400×1500 mm column. To prevent spalling of concrete, fireproof coating and PP fiber are used. As a result, □400×400×1500 mm column was revented spalling likes □100×100×200 mm specimen. When concrete protected failure to explosive spalling, quantity heat atio (which fireproof coating specimen to pp fiber mixed specimen) between □100×100×200 mm and □400×400×1500 mm was maximum value at 20 minute, but difference of quantity heat ratio decreased and quantity heat ratio of each specimen is almost same at 30 minute.
