Kratos FIBERS
Kratos Structural Macro Synthetic Fiber Reinforcement is being produced from the highly resistant raw material Polypropylene according to EN 14889-2 Class II and ASTM C 1116 standards. Highly engineered optimized fiber design ensures a homogeneous 3-dimensional distribution in concrete and Kratos Macro provides allaround crack control by increasing load bearing capacity of concrete under service and design loads of the structure.
KraTos Macro offers the most effective solution against crack formation which is considered to be the weakness of any concrete application. In addition to its superior toughness properties, easy mixing and applicability enables its use in a variety of construction applications including industrial slab-on-ground concretes, screed and topping concretes, specific track slabs, tunnel linings, shotcretes, airport and dock slab-on-ground concretes and precast concrete components.
Presented to the construction market with Kordsa’s own production technology, the CE certified Kratos Macro provides sustainable maximum reinforcement and safety with its unique design to show the highest performance in concrete.
Dosing
The optimum dosing of Kratos Macro depends on the requirements of the specific project. The usual range lies between 2 and 10 kg/m3

Micro Fibers
Kratos Micro Synthetic Fiber Reinforcement is being produced from the raw material Polyamide 6.6 according to the EN 14889-2 Class I standard and provides superior results in terms of preventing early age plastic and long-term drying shrinkage cracks when compared to polypropylene and basalt fibers.
In contrast to other synthetic fibers, Kratos Micro is capable of absorbing up to 5% of the moisture. Moisture that is retained by the fibers when the concrete is freshly poured is reintroduced to the concrete as it sets, resulting in an internal curing effect. This minimizes the formation of cracks due to heat and shrinkage and improves structural integrity.
Areas of Use
Apart from its application in ready-mixed concrete and shotcrete, Kratos Micro can be used in all cementbased composite materials, including semi-dry floor screed applications, interior and exterior plaster applications, construction chemicals manufacturing, repair mortars and similar technical mortar applications.
Dosing
As a result of accredited tests conducted at Aachen University in Germany, it has been proved that the use of 600 g/m3 dosage prevents 99% of the shrinkage cracks.
Packaging
Kratos Micro Synthetic Fiber Reinforcement may be dispensed as water-soluble bags that can be dosed or supplied in big-bags, which are scaled according to project requirements.

Aachen University Accredited Performance Report
Rebound Minimizer
Kratos Rebound Minimizer, a synthetic fiber reinforcement specially designed for shotcrete, is a recent addition to Kordsa’s product range, which reduces rebound in tunnel-driving and mining applications. Kratos Rebound Minimizer fills the gaps between the cement and aggregates, thus reducing the rebound by up to 3-fold.
• Reduces the rebound of shotcrete by up to 70%.
• Specially designed for underground tunnel-driving and mining applications.
• In addition to improving the quality of the shotcrete, it also provides savings in labor and total costs.
Pool Fiber (PX)
Kratos Pool Fiber is a high-performance synthetic fiber reinforcement made from a polymer specially engineered by Kordsa. Thanks to its 3-dimensional homogenous distribution, this product offers effective protection against shrinkage cracks for pool plaster applications. Kratos Pool Fiber is used for cement-based pool plastering applications. The dosage of this product is 150 gr/m3.
• Thanks to its special polymer structure, the fibers do not form clumps and disperse homogenously in the mixture.
• Achieves superior cracking control by minimizing shrinkage cracks that may particularly occur in hot and dry climates.
• Easy mixing and fast application.
• Compared to traditional applications, there is less need for repairs or renewal.
• Offers overall cost savings (labor, time, materials, depreciation, etc.)
