FIRE RESISTANCE OF HIGH-STRENGTH CONCRETES FOR OFFSHORE CONCRETE PLATFORMS

This paper presents the results of the two test programs involving hydrocarbon fires and high-strength concretes. Both lightweight aggregate concrete and modified normal density concrete (blends of normal density and lightweight aggregate coarse aggregates) were evaluated. Small beams of lightweight concrete, using different lightweight aggregate types, were evaluated for spalling resistance. Polypropylene fibers, used in some beams, were successful in greatly reducing spalling. Large wall sections of modified normal-density concrete experienced significant spalling but retained adequate concrete strength behind the reinforcing bars because of the low rates of heat transfer within the large sections.
