PRC-544.10-21: Fiber Effect on Reducing the Permeability of Cracked Concrete Structures—TechNote


Concrete structures are susceptible to cracking during their service life. These cracks become the main route through which liquids and aggressive agents penetrate into and through concrete mass. Does the use of fibers in concrete result in a reduction of crack widths compared to concrete without fibers? Does crack width reduction correlate with maintaining a lower permeability, thus improving the long-term durability of a structure?
