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 […]
