Fibre Concrete Structures – Tests, Design & Applications
Fibre concrete was invented during the second half of the 19th century in USA, but it was not before the 1950s that it received any practical use. Today, fibre concrete is used for rock strengthening, industrial floors, overlays, and small-size precast concrete products. The use of fibre concrete in typical load-carrying structures, e.g., beams and elevated slabs, has, however, been limited. The major reasons are limited experience and lack of codes. In recent years, several structural tests on fibre concrete beams and slabs have been carried out in several countries. The outcome has been mainly promising and some countries have also developed guidelines. The next version of Eurocode 2 is likely to contain an appendix on structural fibre concrete. Steel fibres is the traditional alternative but there are several alternatives, e.g., synthetic (mainly polypropylene), carbon, glass, hemp, and basalt. They have different advantages and disadvantages. In recent years, the use of basalt fibres have increased. Compared with steel fibres, basalt fibres have two advantages; (i) they have similar density as concrete implying less segregation risk and (ii) they do not corrode. This paper covers some Swedish experiences with fibre concrete structures by summarizing some tests, design specifications, and applications. ; QC 20201014
