First Use of Lightweight High-Performance Concrete Beams in Virginia
The paper describes an experimental program to demonstrate the feasibility of using lightweight high performance concrete (LWHPC) bridge beams and decks. These prestressed beams had a minimum 28-day compressive strength of 8,000 psi and the deck concrete had 4,000 psi. The beams had maximum permeability of 1500 coulombs, and the deck concrete had 2500 coulombs. The beams were required for an LWHPC demostration bridge being built in Charles City County-New Kent County border line in Virginia.
