Abstract:
Restrained shrinkage tests were carried out on ring specimens of concrete reinforced with polypropylene fibers. These fibers had a relatively improved modulus of elasticity and enhanced bond with portland cement matrix. To achieve uniform dispersion for the relatively high fiber content (2 percent volume fraction) employed, a conventional pan mixer was attached with a high-speed activator. It was observed that even after severe drying, no visible cracks (cracks wider than 0.01 mm) appeared on the polypropylene fiber reinforced specimen.
