Title: Cracking Histories of Synthetic Fiber Reinforced Concrete Applications
Author(s): Clifford N. MacDonald
Publication: Special Publication
Appears on pages(s): 1-10
Keywords: fiber reinforced concrete, FRC, synthetic FRC, theoretical mechanics, projects
Abstract:In 1994, the bridge over Interstate 90 at mile marker 212 in South Dakota, USA, used synthetic fiber reinforced concrete in the approach, deck topping, and Jersey barriers. Crack widths were measured and counted on the three applications with a histogram developed for the Jersey barrier. The synthetic fiber dosages were 1.3% and 1.6%. This location and applications have been monitored almost yearly and more thoroughly in 2007. Comments, including crack history, on other applications placed 1994 to 1995 and 2002 to 2006 are included for comparison. Further comparisons include synthetic fiber reinforced concrete with and without conventional steel reinforcing, and with plain concrete. There is a significant measurable difference in crack frequency and width with a decided benefit from synthetic fiber reinforcement. The historical and philosophical review is accomplished with selected examples of synthetic fiber reinforced concrete projects to allow for a generalized beneficial conclusion.
