Tom,
Thanks for the reply. As mentioned, after considering 5000psi concrete & silica fume, can concrete take temperature around 200 degree centigrade, without provision of any inside insulation. Reply for the same will be highly appriciated.
Thanks

Bhavin,
There are a couple of PCA documents that indicate for non-fire related cases concrete can sustain continuous temperatures up to approximately 400 degree F. Temperatures over 500 degree F will definitely cause deterioration. ACI 349 for Nuclear Facilities takes a very conservative approach and limits concrete temperatures during normal operation to 150 degree F and 200 degree F for local areas such as wall penetrations and for accidental or short term exposure 350 degree F and 650 degree F for localized steam or water jets. For a sulphur storage pit be sure to specify a high performance concrete with minimum 5000 psi with a good mineral additive such as 7 to 10 percent silica fume.

Please respond to seaint
To"seaint@seaint.org" <seaint@seaint.org> cc SubjectMax. temperature for concrete
Pl. let me know that what is the maximum temperature bare concrete can withstand, in case of liqquid sulphur storage pit (concrete strength = 4000 psi, crack free design).
Thanks
