not fail.i want to know can it withstand a temprature of 500 degree celsious inside an enclosed area.

It depends on the concrete mix.
This is really something that can be answered by an engineer. You need to give him the dimensions, required load bearing strength and support structure information.
With that and the maximum temperature you are expecting, he can tell you if it is possible, what the mix characteristics and reinforcement requirements are.
Most concrete used in structures can loose strength in a hot fire. It does happen that after a house fire the foundation is no longer solid enough to keep.
It isn't about the temperature to melt rock, just the temperature to weaken the bonds in the masonry.

Your question is extremely hard to answer because there are so many influences that go into concrete and it's strength. Even before it is poured different strengths and additives can be ordered that will alter its strength. As far as maximum heat that concrete will with stand would exceed any temperature from a normal house fire. Were talking about temperatures that would melt rock or steal that would exceed thousands off degrees. Normal heat will not have any effect on the concrete's strength what so ever.

As far as the temperature is required the RCC can withstand satisfying the following criteria's to be favourable
a) The conrete mix by which the structure is made.
b) The grade of steel used in the construction.
c) The effective cover provided to the steel.
d)The type of structure based on its use.
As the temperature increases in the structure the steel releases the stress induced in it and become plastic resulting in the failure.

based on the integrity of the constituent properties of the concrete add mix values,basic standard concrete will withstand heat temperatures of120 Celsius 250 F.

No undertaking with concrete and warmth. reinforced concrete, if it replaced into designed using the ACI development code, and if the oven is right built in line with hearth codes, then there could be no undertaking. Insulation on the backside of the oven will decrease the pass of warmth. Civil Engineer
