Why not just use concrete unprotected?

Concrete does not burn, but when exposed to rapid thermal impact it will spall either progressively or explosively. CAFCO® FENDOLITE® M-II provides predictable performance under fire and prevents concrete from spalling under the most severe fire exposure conditions. CAFCO FENDOLITE M-II is more resistant to cracking and spalling compared to concrete. It prevents concrete spalling under impact and thermal shock and is more resistant to effects of deluge water. If damage to the spray fireproofing system occurs, repair is quick and easy and traditionally do not require tunnel shut-down.
