FIBRE REINFORCED CONCRETE
There are a number of factors that influence the behavior and strength of SFRC. These include: type of fibre, fibre length, aspect ratio of the fibre, the volume fraction of the fibre, fibre orientation and fibre shape.
Aspect Ratio (AR) is the ratio of fibre length against the diameter (I/d). The higher the AR and volume concentration of the fibres, the better is the performance with respect to the flexural strength, flexural fatigue, toughness, abrasion, impact and crack resistance.
Equivalent Flexural Ratio, Re,3 is defined as the ratio between the equivalent flexural strength, fe,3 and concrete strength, fct at which the first crack occurs. The design flexural strength, fa takes into account the plastic moment distribution after the concrete crack. The higher the Re,3 value, the better the concrete performance.
The main purpose of STAHLCON steel fibre is to increase the energy absorption capacity and toughness of the concrete which grant it with superior crack resistance. Steel fibres suppress and bridge the cracks in the concrete matrix hence avoid total loss of the bearing capacity after first crack (which happens in brittle fracture) by enhancing the concrete matrix a ductile behaviour.
Steel fibres are commonly used in shotcreting, commercial as well as industrial floors with heavy loadings. Steel fibres is able to be applied as an addition or a total replacement for conventional steel bars or meshes in its applications.
