Abstract:

The national transportation network contains a significant number of highway and railway bridges. This research is intended to transform the use of precast/pre-stressed materials in the transportation infrastructure. Specifically it examines how nanoporous thin-films create a new jointing mechanism between precast concrete bridge components. Mechanical testing was conducted from which it was determined that these thin-films can increase the bonding strength of grout in joints. Preliminary durability testing was performed and showed these thin-films help strengthen the jointed area. Lastly, Scanning Electron Microscopy was used to help better define the mechanism by which the thin-films improved the bonding strength of grout to hardened concrete.
