Used as secondary reinforcement, polypropylene fibers help raeduce shrinkage and control cracking. To use these fibers, concrete mix design does not have to be altered, and no special equipment or slump modifications are required, even for pumping or shotcreting. Only two things must be determined: how much fiber to add and what length of fiber to use. Polypropylene fibers are manufactured in small bundles. During the mixing operation, the movement of aggregate shears these bundles into smaller bundles and individual fibers. If the jobsite is more than a 30-minute drive, the fibers should be added at the site.
