Definitions
- Fibers can introduce toughness (i.e., energy absorption capacity during failure) to concrete, overcoming its intrinsic brittleness and providing post- cracking strength under direct or indirect tensile stresses.
- the vast majority of conventional fibers used for reinforcing concrete reinforcement are made out of low or high carbon content steel, or polymers such as polypropylene, polyvinyl alcohol, polyester, etc. These conventional fibers suffer from limitations. Processability issues can be generated by the relatively high dosages required (such as clustering during mixing, blockings during pumping, reduction of workability, and difficult compaction and finishing).
- Composite reinforcing materials can overcome the shortcomings of conventional fibers; i.e., by achieving a very high performance at relatively low dosages.
- JP2002154853 Al describes composite fibers produced by impregnating a continuous inorganic fiber bundle with a resin, hardening the resulting material and thereafter cutting the hardened material.
- the resin content of this composite fiber is 10 to 80 mass %. Its length is 10 to 80 mm and its cross section is 0.1 to 12 mm.
