Fibre Distribution In Macro Plastic Fibre Reinforced Concrete Slab Panels

The side walls slightly redistribute the fibre orientation as the transverse dimension of the slabs is reduced.

Fibre distribution in macro plastic fibre reinforced concrete slab panels.

For 4 to 6 inch thick slabs aci recommends joint spacings from 8 to 15 feet for somewhat square slab panels based on a number of factors such as concrete shrinkage potential. 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. 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. 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.

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. We would like to show you a description here but the site won t allow us. 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.
