Fibre Concrete – Swedish Research & Experience
Fibre concrete has been used in Sweden and many other countries during more than 50 years despite that it has not been fully recognized by the code writers. In Sweden, the use of steel fibre concrete is extensive in two applications; shotcrete for strengthening rock tunnels and industrial concrete floors. This paper describes briefly these two applications as well as two other rather common applications; precast concrete elements and concrete overlays. Recent European and national Swedish standardization works have opened the fibre market for structural applications such as beams and elevated slabs. This paper summarizes the new Swedish standard. A problem with fibre concrete is the large scatter that is connected to the flexural tests on SFC beams that constitute the bases of design. The Swedish standard includes a novel concept of discerning between statically determinate structures and statically indeterminate structures. The latter has ability to stress redistribution and this beneficial circumstance has been taken into account by including a magnification factor in the design. Finally, the paper summarizes Swedish field tests on a column-supported SFC slab. The results were promising and have constituted support for the Swedish design. ; QC 20201014
