Project 2.04: Thermoplastic Composites by 3D Printing and Automated Manufacturing to Extend the Life

Thermoplastic Composites by 3D Printing and Automated Manufacturing to Extend the Life of Transportation Facilities Project 2.04

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

High Performance Concrete with Post-Tensioning Shrinking Fibers Project 2.07 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 […]
