FIRE ENDURANCE OF HIGH-STRENGTH CONCRETE SLABS

In recent years, use of high-strength concrete ranging in compressive strength from 8000 to 15,000 psi has become more prevalent. Concrete structures, such as high-rise buildings, are now using these materials. Most recently, the use of silica fume as a supplementary cementitious material has developed for design of higher strength concrete mixtures. The objective of this investigation was to develop fundamental information on the behavior of high-strength concrete at elevated temperatures using realistic test specimens. Scope of the work included a review of available literature on performance in fire tests of specimens fabricated fron high-strength concrete mixtures, with and without silica fume. The literature review was followed by laboratory tests of 3 x 3 x 0.33 ft slab specimens with embedded reinforcement. Specimens were exposed to elevated temperatures and monitored for temperature rise and physical integrity. Tests were conducted at the Fire/Thermal Technology Section of Construction Technology Laboratories, Inc. (CTL). Results of fire tests performed on the slab specimens show no measurable difference in performance of high-strength concretes and conventional strength concretes.
