Micro Synthetic Fibers are thin and short fibers produced from polypropylene, polyester or other synthetic materials. These fibers are used to control microcracking formation of concrete and mortars.

Micro Synthetic Fibers help prevent the formation of cracks in plastic concrete, increase the friction resistance of hardened concrete and improve overall durability.

Micro Synthetic Fibers are resistant to corrosion, have a lighter structure, provide a homogeneous distribution in concrete and do not carry the risk of electrochemical reaction.

It is used for micro-crack control in thin-layer concrete coatings, screeds, prefabricated elements and sometimes construction concrete.

No, they are added directly to the concrete mixture and dispersed homogeneously by mechanical mixing.

They are generally millimetric in length and have a very thin structure. Different manufacturers offer fibers of different sizes and geometries depending on the requirements of the application.

The cost varies depending on the manufacturer, the properties and quality of the fiber, and the quantity used.

They generally do not adversely affect the workability of concrete. However, when used in very high doses it may have an impact on workability.

Micro Synthetic Fibers do not directly increase the tensile strength of concrete, but they extend the service life of concrete by controlling micro crack formation.

Micro Synthetic Fibers are long-lasting as they pose no risk of corrosion and are produced with less energy than steel fibers, making them a more sustainable option.

Micro Synthetic Fiber

Micro synthetic fiber reinforcements are used to minimize plastic shrinkage cracks and plastic settling cracks in concrete. Monofilament fiber bundles made of pure polypropylene show homogeneous distribution in the concrete, reducing sweating and increasing the early age resistance of the concrete. Micro synthetic fiber reinforcements, which are extremely easy to use, also increase the impact resistance and surface wear resistance of the concrete throughout its service life.

Another positive effect of micro synthetic fiber reinforcements, which are 100% alkali resistant, on concrete is to increase the freeze-thaw resistance of concrete.
It is used to provide passive fire resistance in tunnel concrete production, which is one of the common usage areas of micro synthetic fiber reinforcements. Micro fiber reinforcements dispersed to every point of the concrete prevent the concrete from dispersing during a fire and ensure safety in the tunnels.
