i have a building designed for 2 hours fire rating .
The structure of building is RCC column and beams .
due to some reason we have to repair the beam at support near the columns .
the repair was done with fibre carbon and fire retarder was applied over that as no intumscent paint was compatible with this material . we use Albi coat class A material
can we derive this( Fire retarder )material in terms of fire rating .
if yes? according to which reference standards.
