MECHANICAL CHARACTERISTICS OF HIGH PERFORMANCE FIBRE REINFORCED CONCRETES AT ELEVATED TEMPERATURES
This paper investigates the effect of high temperature on the mechanical characteristics and spalling tendency of different grades of concretes reinforced with 0.5% per volume of steel or polypropylene fibers. A total of 9 concrete mixtures were produced and fibers were added in 6 of them. At 4 months, the specimens were heated to maximum temperatures of 100, 300, 500, and 700 deg C. Specimens were then allowed to cool in the furnace and tested for compressive strength, splitting tensile strength, modulus of elasticity, and ultrasonic pulse velocity. Addition of steel fibers increased the percentage of residual strength up to 300 deg C, but spalling still occurred in some concretes tested at temperatures up to 700 deg C. Such explosive behavior was not observed when polypropylene fibers were added to the mixtures.
