KRATOS MICRO

KraTos Micro Synthetic Fiber Reinforcement, on the other hand, is widely used in all kinds of infrastructure and superstructure projects as a shrinkage reinforcement material to prevent early-age cracking.

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 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 plasters and mortars.

Dosing

The effective dosing range is between 0.45 kg/m3 and 0.90 kg/m3 and may vary depending on the application and performance requirements.

Packaging

KraTos Micro fibers may be dispensed as watersoluble bags that can be dosed or supplied in big-bags, which are scaled according to project requirements.

  • Whether in individual packets or big-bags, KraTos Macro is supplied in water-soluble PVA bundle for homogeneous mixing and easy applicability.





    Mixing and USAGE    
   
KraTos Macro in 1 kg water-soluble packets is added into the concrete mix. After adding all packets to the concrete, the concrete mixer is run at top speed for at least 5 minutes.   KraTos Macro bundles are added to the aggregate conveyor to mix the concrete in the batching plant. A homogenous mixture is obtained in the RMC plant followed by mixing in the concrete mixer.   KraTos Macro, which is supplied in big-bags to the RMC plant, is added to the mix at a constant rate with the help of a dosing machine.
         
   
After the last bag is added, mixing at top speed for 5 minutes opens the bundles and ensures a homogeneous distribution.   The KraTos Macro concrete application guarantees a perfect surface finish. The fibers do not harm the pump or any other equipment.   KraTos Macro increases the adherence of shotcrete and minimizes rebound.
SAVING ON LABOR + COST + TIME

KraTos Macro offers ease of application and is compatible with any class or slump of concrete. KraTos Macro is designed to minimize the slump loss in the concrete and to ensure rapid and homogeneous distribution in the mix.

KraTos Macro completely eliminates wire mesh placing and anchoring applications to reinforce the concrete. The direct application of reinforced concrete offers up to 40% savings in time and reduces the total cost of ownership. It prevents handling errors, improving the quality of the application and increases work safety by preventing occupational accidents associated with the application of wire mesh.

The fact that KraTos Macro is easier to pump or spray compared to the competition results in a high-quality execution and prevents errors such as adding excessive water to the concrete mix. Easy passage through the concrete pump or the grade of machine ensures an effective application. In contrast to polypropylene fibers that tend to rise to the surface when used in concrete floors, due to its higher density, KraTos Macro does not remain on the surface, thereby saving labor costs related to surface finishing and adding a time benefit.

Industrial Flooring

Industrial flooring is a concrete floor system that aims to prevent wear using special protection or coating solutions and is designed to meet the end user's needs with special consideration given to esthetics (such as surface color, tining, curing, etc.).
The use of KraTos Macro in industrial flooring applications provides 3-dimensional strength and effective crack control. Pouring concrete with pump and wire mesh placing applications will be eliminated. KraTos Macro homogeneously distributes in the concrete, can easily be poured using a mixer and is readily applied at any consistency. As a result, it provides direct and indirect cost savings for the project.

Screed, Topping and Slab on Ground Concrete

Screed must perform well in limited sections considering the level of the building. Insufficient concrete thickness or early dehydration may cause curling of the screed. This curling may lead to crack formation over time. The 3-dimensional distribution of KraTos Macro in the concrete minimizes curling and thus prevents crack formation. Consequently, fractures at the joints and corners are also prevented. Easy handling of the material speeds up the completion of works and provides economic benefits.
Similar to screed, topping concrete, too, requires a high performance in limited sections. The use of KraTos Macro in topping concrete improves impact resistance, prevents extra loads on the structure and offers fast and crack-free application.

Concrete Roads

Concrete roads are usually built by placing concrete slabs on the ground. The function of concrete as a road pavement material is to reduce the traffic load to a level that would not cause deformation before transferring it to the ground. Project-related factors that are considered when designing a concrete road include traffic, weather conditions, the loadbearing capacity of the ground, mechanical properties of the concrete slabs, economic service life and expected service quality of the road. The use of KraTos Macro in concrete roads improves the fatigue resistance of concrete under repeated loads, prevents the formation of longitudinal cracks and faulting and extends the service life of concrete by adding chemical resistance. The homogeneous distribution of the material in concrete makes it resistant against the effects of freezing and thawing.

Port Projects

Port structures are highly susceptible to the effects of humidity, wind and salt water. Replacing conventional reinforcement with KraTos Macro helps to avoid corrosion, provides effective crack control by 3-dimensional fiber reinforcement and thus extends the service life of the structure and improves its impact resistance. Compared to conventional methods, pouring KraTos concrete reinforced with saves up to 40% time, which, together with the elimination of reinforcement work, translates into cost advantages for the project.

Hydraulic Structures

Hydraulic structures are expected to have a long service life. Concrete reinforced with conventional means is subject to early degradation and corrosion due to the impact of ground and surface waters. This type of concrete structures reinforced with KraTos Macro is not exposed to the detrimental effect of corrosion and offers a long service life as planned. Its effective and easy use during construction expedites the project.

Tunnel Lining

In tunnel lining, time and safety are the two most important parameters. The use of KraTos Macro reinforced concrete lining provides ductility and prevents sudden collapse. KraTos Macro eliminates steel reinforcement application and saves time to the tunnel construction project. Exposed to groundwater, steel reinforcement might incur sectional loss due to several reactions. Therefore, reinforcement that is resistant to corrosion extends the service life of concrete.
Fire resistance is the most important safety concern in any tunnel construction. As KraTos Macro synthetic fibers have no thermal conductivity, they do not contribute to the heating of cement as steel wires or other reinforcements would do in case of fire. Similar to other polypropylene fibers, KraTos Macro has a high melting temperature, which helps to preserve the structural integrity of the tunnel lining after a fire.

Shotcrete Lining

Using KraTos Macro synthetic fiber reinforcement in shotcrete instead of wire mesh may help to shorten the project time by up to 40% depending on the surface class. Placing wire mesh in a tunnel is a challenging work that may lead to accidents. As the surface gaps are heterogeneous, the wire mesh may not be laid out so as to cover the concrete evenly, which results in 50% more shotcrete use and faulty applications. Using shotcrete reinforcement with non-corrosive KraTos Macro fibers improves work safety, extends durability and saves time and money for the project.

Track Slabs

The use of KraTos Macro fiber reinforcement in the construction of railway systems eliminates reinforcement applications, ensuring the most convenient application and saving at least 30% of time. The most important safety concern related to railway systems and track slabs in particular is electrical conductivity.
Non-conductive KraTos Macro synthetic fibers provide maximum safety. Its 3-dimensional strength and resistance translate into high performance after crack formation by holding the concrete together.

Precast Concrete

The use of fiber reinforcement in precast concrete imparts a high durability to the application. Compared to steel mesh, its easy application saves both time and labor costs. Its corrosion resistance protects the structure in the long-term against unfavorable external factors such as groundwater.
