Premco PolyMacro

Premco Macro Concrete Fiber

Structural macrofiber made of modified polyolefin. Perfectly distributed in the volume of concrete mix, the fibers create a highly effective three-dimensional concrete reinforcement system.

Usage

PolyMesh® fibers are added to concrete at any stage of concrete production. Place the required amount of water-soluble bags with fiber in a concrete mixer. For an even distribution of the fibers, it is necessary to mix the grout for 6-8 minutes. Before applying fresh concrete at the construction site, the concrete mixer must be spinned at maximum speed for 2 minutes. PolyMesh® fibers are designed in such a way that, when mixed with other components, they are evenly distributed throughout the volume of the grout.

Dosage

The minimum dosage for PolyMesh® starts at 1 kg/m3. The recommended dosage range for PolyMesh® is from 2 to 8 kg/m3. Used in the appropriate dosage, PolyMesh® is the ability to replace steel fibers, welded wire mesh, or significantly reduce steel bars reinforcement. PolyMesh® fibers are a safe and easy-to-use alternative reinforcing system that is stable in alkaline concrete where high chemical resistance is required.
