Project 2.07: High Performance Concrete with Post-Tensioning Shrinking Fibers

High Performance Concrete with Post-Tensioning Shrinking Fibers Project 2.7 Project Summary This research improves upon the technique of reinforcing concrete with dispersed fibers by having the fibers axially shrink after curing to produce a dispersed multi-axial post-tensioned state. Such reinforcing may increase the crack resistance and durability of the concrete. Preliminary benchtop testing with natural […]

Project C07.2018: Alternative Cementitious Materials (ACMs) For Durable and Sustainable Transportation Infrastructures

Alternative Cementitious Materials (ACMs) For Durable and Sustainable Transportation Infrastructures Project C7.2018 Project Summary Concrete produced with Alternative Cementitious Materials (ACMs) often exhibits superior mechanical performances and lower carbon footprint compared to those produced with Ordinary Portland Cement (OPC). ACMs also allow utilizing high-volume of industrial by-products as the binding materials instead of OPC, thus […]

Project C05.2018: Leveraging High-Resolution LiDAR and Stream Geomorphic Assessment Datasetsto Expand Regional Hydraulic Geometry Curves for Vermont: A Blueprint for NewEngland States

Leveraging High-Resolution LiDAR and Stream Geomorphic Assessment Datasets to Expand Regional Hydraulic Geometry Curves for Vermont: A Blueprint for New England States Project C5.2018 Project Summary Regional hydraulic geometry curves (RHGCs) for Vermont have been updated through development of additional observations and use of newly-available high-resolution lidar and stream geomorphic assessment data to improve the […]

Project 2.10: Durability Evaluation of Carbon Fiber Composite Strands in Highway Bridges

Durability Evaluation of Carbon Fiber Composite Strands in Highway Bridges Project 2.10 Project Summary The objectives of this project are to monitor the structural performance of carbon fiber composite cable (CFCC) strands in the Penobscot Narrows Bridge, a cable-stayed bridge, to evaluate long-term durability, and to assess durability of carbon fiber reinforced polymer (CFRP) strands […]
