Project description

This research aims to develop a prescriptive and performance-based specification that states could adopt to ensure the required performance in both crack resistance and contractibility of the fiber reinforced concrete. This specification would use the Split Beam Test, ASTM C 1609, creep, and the Float Test to set performance limits for the different fibers. This performance could then be specified based on the required performance or safe dosages of fibers could be prescribed based on the member. For example, a sidewalk, overlay, and bridge deck may have different performance criteria.
