Title: Fiber Reinforcement for Minimizing Spalling in High Strength Concrete Structural Members Exposed to Fire
Author(s): V. K. R. Kodur

Abstract:The increased use of high strength concrete (HSC) in buildings has raised concerns regarding the behaviour of such concrete in fire. Spalling at elevated temperatures and the resulting reduction in fire resistance is of particular concern. In this paper, the various issues relating to spalling and its impact on fire resistance are discussed. The mechanism of spalling is explained and the main causes for the occurrence of spalling in HSC are described. The various parameters that influence spalling in HSC under fire conditions are discussed. Results from the experimental studies are presented to illustrate the effectiveness of polypropylene fibers in minimising spalling in HSC structural members.
