Concrete Structures Restoration from the Fire Safety Point of View

The need of concrete structures restoration in order to ensure their fire resistance can, in engineering practice, occur for reasons of damage to the structure by fire (spalling of concrete cover layer) or by the failure to cover the load-bearing structure during construction. The paper is devoted to the evaluation of the structure cover of the evaluated structure, the determination of temperature distribution in the structure with consideration to the choice of probable fire scenario, subsequent determination of critical temperature of the structure and the optimization of possible methods of the restoration of damaged or wrongly made constructions.
