ELEVATED TEMPERATURE EFFECTS ON HSC RESIDUAL STRENGTH

Concrete is generally thought of as being an excellent fireproofing material. With the evolution of high-strength concretes (HSC), questions have arisen as to whether these types of concrete, with significantly reduced porosity, can still be effective as a fireproofing material. Because of concerns about the use of HSC in facilities for the production of oil and gas where hydrocarbon fires are not uncommon, a joint industry/government multiphase research program was initiated to examine the effects of hydrocarbon fires on HSC. This article examines the residual strength determinations for 3 different types of HSC used in oil and gas facilities: normal density concrete, lightweight concrete, and an intermediate density concrete called modified normal density concrete. Materials used, preparation and casting of test specimens, testing and results, and conclusions are discussed.
