Abstract |
Applying fire resistive coating to steel members is one of the general methods to secure fire resistance performance of steel members. And intumescent coating system is currently one of methods giving fire resistance to steel members.Intumescent coating system for fire resistance, however, has undesirable weaknesses that fire resistance performance of steel members is being deteriorated due to cracks and falling-offs of the coverings as time goes after completion of the coverings to the members. So it is necessary to understand changes of the fire resistance performance and durability of the intumescent coating system over a time elapse and to reflect such change properly into the building design and construction.This study is designed to understand changes in durability of intumescent coating system through follow-up tests on temperature of unexposed surface and bond strength for the domestic intumescent coating system. |
