Structural Fiber Reinforcement to Reduce Deck Reinforcement and Improve Long-Term Performance (Jun 2020, MPC-20-413)
Jared W. McRory, Fray F. Pozo-Lora, Zachary Benson, and Marc Maguire

The use of deicing salts on highway bridges has decreased the service life of bridge decks due to the accelerated corrosion of the steel reinforcement. The use of Glass Fiber Reinforced Polymer (GFRP) in bridge decks as a means of corrosion-mitigation has been met with some success; however, GFRP is...

 
Calcium Sulfoaluminate Cement Concrete for Prestressed Bridge Girders: Prestressing Losses, Bond, and Strength Behavior (Dec 2019, MPC-19-401)
Nicholas A. Markosian, Robert Thomas, Marc Maguire, and Andrew Sorensen

Calcium sulfoaluminate (CSA) cement was used to cast a prestressed voided deck slab bridge girder. The rapid-set properties of CSA cement allowed the initial concrete strength to reach the required 4300 psi needed in order to cut the prestressing strands 6.5 hours after casting. Prestress losses were...
