APPLICATION OF FRC TO PIPES OF SEWERAGE PIPELINE SYSTEMS

摘要

This paper describes recent application of fiber reinforced concrete to reinforcing of pipes of various sizes and with various fibers, which have been used in practice. The fibers used are steel fibers Fibrex and Arcelor, and synthetic fibers Forta Ferro. The effect of the fibers is compared among each other and with reference plain concrete. Fibre concrete as a specific building material have been investigated and used for decades in the world and the tradition of research, development and utilization is long also in the Czech Republic. So far the use of fiber reinforced concrete has been limited only to industrial floors, tunnel linings, and structures where it is necessary to eliminate the number, width and depth of cracks in curing concrete, or to a composite material for precast production of members of various sizes. An example of application of fiber reinforced concrete long-term research results in practice is represented by substitution of the conventional rebars in reinforced concrete pipes with fiber reinforced concrete in precast concrete production.
