Fibre Distribution In Macro Plastic Fibre Reinforced Concrete Slab Panels

Cost and environmental benefits and applications of fibre reinforced concrete are discussed.

Fibre distribution in macro plastic fibre reinforced concrete slab panels.

Additionally a computed tomography ct scans was for the first time successfully applied to assess the amount of macro plastic fibres as well as its distribution and orientation in a prismatic core. These unique fibers add superior bonding properties to the concrete matrix. The addition of fibres provides enhanced.

Sikafiber force 600 is a macro synthetic fiber designed for maximum performance in shotcrete application and as a replacement for welded wire mesh wwm in a wide range of concrete applications from industrial slabs on grade to precast structures. Degradation and pull out behaviour of macro plastic fibre in concrete are reviewed.

This composite has proven to be a competitive material in many types of structures in several of them fibres are used for structural purposes substituting partially or completely the conventional reinforcement. We would like to show you a description here but the site won t allow us. The result is crack control and an extended service life of the concrete synthetic macrofibers are manufactured from a proprietary blend of polypropylene resins in compliance with astm c 1116 c 1116m. Biddle says dosage rates of macro fibers between 3 to 7 1 2 pounds per cubic yard of concrete produce slabs with reduced shrinkage and curling.

The fibers for micro products are made primarily from nylon or polypropylene each having the same effect on concrete while macro fibers are typically made of polypropylene and related co polymers. Another recommendation is that the maximum slab aspect ratio length to width should be 1 5 1 in order to minimize the possibility of transverse cracks. Fibre reinforced concrete frc is one of the most relevant innovations in the field of special concretes. Macro plastic fibre reinforced concretes show excellent post cracking performance.
