2022-2-2  Round-shaped steel fibers are the most common type used in fiber-reinforced concrete. Steel fiber in concrete is often used for road pavement overlays, bridge decks, and airfield pavement. Glass fibers in concrete can be used for more modern and aesthetically pleasing, lower-weight structures, like furniture or architectural claddings on buildings.

Experimental and theoretical investigation of the shear

Short steel fibres have been introduced into prestressed concrete X beams in order to study their behaviour under shear loads. The X beams, which have circular web profiles, were chosen to represent longitudinal sections from 215 mm deep prestressed precast hollow cored floor units, which are known to fail in shear in a brittle manner.

Two types of steel fibre were investigated: hooked-end steel fibres at fibre volume fractions (Vf) of 0.5%, 1.0% and 1.5%; and amorphous metal fibres at Vf‘s of 0.28% and 0.56%. The trial production of fibre reinforced hollow core slabs necessitated the investigation of the effect of steel fibres on the extrusion manufacturing process.

Steel fibre reinforced concrete BECOSAN®

2020-4-7  Steel fibre concrete is a type of reinforced concrete. It’s basically made up of cement, water, sand, gravel and steel fibres. In some cases additives are added. Steel fibres are discontinuous and isotropic, short metal reinforcements similar to metal filaments or threads. These can be corrugated, wavy or smooth, with flat or shaped ends.
