Structural steel fibres for concrete flooring

Code: RDM.0212

Components: 1

Appearance: Fibers

"Carbon steel fibres, obtained by the cutting of metal wire, with improved adhesion profile, for three-dimensional general structural reinforcement of cement-based conglomerates. The addition of READYMESH MF-500 significantly increases the mechanical performance of the structure in terms of toughness, ductility, fatigue, dynamic stress, shock, wear, tensile and shear strength and even post-cracking and damage behaviour."

Use fields

General preparation of fibre-reinforced concrete and structural sprayed concrete (e.g. shotcrete). Particularly suitable for high strength industrial flooring and prefabrication.

Use method

"READYMESH MF-500 fibres must be added to the concrete during mixing. It is recommended to pour the fibres directly onto the loading belt of the concrete mixer during the loading of the aggregates. Alternatively, it is possible to add them directly into the mixer after loading the concrete. In this case, add the fibres a little at a time so that they are well-distributed in the cement mix and extend the mixing time by at least one minute for every 20 kg of fibres added in order to achieve optimal distribution.

Conglomerates with READYMESH MF-500 can be easily transported and used with pumps, joiners, vibratory finishing machines, roadway extruders (e.g. slipform paver), etc."

Application methods

- To be added to other components

Permitted supports

- Concrete

- Prefabricated concrete

Warnings, precautions and Ecology

Improper addition of the fibres to the cement mix may cause substantial alterations to the mechanical performance of the concrete itself.
