THE PROPERTIES OF CONCRETE REINFORCED WITH MELT-EXTRACTED FIBERS ---NORDIC CONCRETE RESEARCH

The objective of this paper is to present the experimental investigation of concretes with 1 and 2 percent of melt-extracted steel fibers by volume. Mixing methods for fiber were tried on trial mixes. The compressive, tensile and flexural strength were measured. The results of tests on the fracture energy, bond and punching strength are also presented. The long-term effects are evaluated on the basis of creep and shrinkage tests for 60 days. Moreover, bending tests on repaired concrete beams and impact tests on slabs are shown as part of the investigations towards possible applications of concrete modified with fibers. The test results showed that melt-extracted steel fibers are effective in improving some concrete properties and made it possible to compare to other types of fiber.(a) for the covering abstract see IRRD 816919.
