Abstract:
Processed cellulose fibers provide a highly desirable balance of mechanical, geometric, and durability characteristics for the reinforcement of cement-based materials. Specialty cellulose fibers have been developed for use in conventional concrete mixtures using normal mixing procedures. This research assessed the effects of specialty cellulose fibers at relatively low dosages on the fresh mix workability and finishability, restrained shrinkage cracking characteristics, strength, toughness, impact resistance, bond strength to deformed bars, and durability of concrete. The use of specialty cellulose fibers in mortar and high early-strength concrete mixtures is also investigated.
