They are long synthetic fibers produced from high molecular weight polymers such as polyolefin or polypropylene. It makes concrete more durable by intervening in micro-level structural defects.
These fibers extend the service life of concrete by increasing its resistance to early age cracks. By restricting the capillary movement of water, it reduces the water absorption capacity of concrete and increases its resistance to corrosive effects.
Compared to steel fibers, these synthetic fibers pose no risk of electrochemical corrosion. It also provides a more uniform distribution within the concrete and has the potential to reduce labor costs because it requires no special alignment or placement.
It is frequently preferred in non-structural and structural concrete applications with high performance requirements. These include structures in earthquake zones, high traffic floors, water structures and tunnels.
Integration of Macro Synthetic Fibers is simple. They are added directly to the concrete during the concrete batch process and are easily dispersed by mechanical mixing.
The fiber geometry is optimized according to the specific needs of the application. Hydrodynamic design and variant dimensions are used for optimal distribution and performance.
In general, the quality of the polymer used in the production of the fiber, fiber geometry and the total usage amount are the main factors affecting the cost.
When used in optimal proportions, these fibers do not adversely affect the workability of concrete, although in some cases the water/cement ratio may need to be slightly adjusted.
It shows a significant improvement in the tensile strength of concrete. While it increases impact and wear resistance, it may not have a direct effect on compressive strength.
The production of Macro Synthetic Fibers is more sustainable and energy efficient compared to steel fibers. No risk of corrosion extends the service life of structures and further reduces their environmental impact.
