Abstract:
Polypropylene fibers are synthetic fibers used for crack control in concrete. While all polypropylene fibers rely on frictional bond to engage the concrete matrix, a new type of fiber incorporates compounds capable of creating chemical bond. The new fibers are described and ASTM test results are used to compare the performance of the new fibers with traditional polypropylene fibers.
