Parametric Analysis of the Durability and Chloride Penetrability of Fiber Reinforced Concrete Bridge Decks

The primary objective of this research project is to reduce the uncertainty related to the fiber dosage rate and fiber dosage-to-paste volume ratio in fiber reinforced concrete mixes used in UDOT construction. By parametrically studying the effects of different fiber dosage rates on specific performance criteria, an ideal fiber dosage amount can be determined. The main performance criteria for optimization include strength, workability (ease of placement), long term durability (as a function of freeze/thaw and chloride penetration resistivity), and toughness (ability to flex with minimal cracking).
