Re: Concrete Cover

[Subject Prev][Subject Next][Thread Prev][Thread Next]


In addition to considering the effect of reduced concrete cover on the fire
rating and weather protection of the reinforcement, you should also consider the
effect it has on the development and splice lengths of the reinforcement.
Especially since there is less than a bar diameter of cover.
