Concrete hardener (Hardener)

There are some weak points in hardened concrete such as low abrasion resistance, dust making, low resistance against shocks, penetrable against environmental factors, unwanted porosity, lack of chemical resistance and so on. Therefore, it is recommended to use hardeners for increasing the quality of concrete surfaces. These materials not only cover most of above-mentioned weak points but also make it possible to have beautiful & harmonized surfaces. For reaching to the mentioned ideals, Zorlu Co. has provided concrete hardeners. Hardener is a ready cement powder composition with soft parts and could be used by dry spraying on fresh concrete. All areas which have been dried spray would be completely smooth and harmonized for further resistance against abrasion. This product has a considerable adhesion to below-layer concrete and may increase its durability by reducing of permeability.
 
Some of the advantages of concrete hardener are high economic priority, economic condition, increasing the shock resistance, increasing abrasion resistance, Anti Dust, Anti Electrostatic, easy wash, integration of concrete, easy & quick performance, nonflammable, low thickness, Non-slip in oily & wet conditions, suitable integration to below layers of concrete and lack of separation from the surface, resistance against oil, grease and benzene penetration, Anti UV and variety in color. According to the above-mentioned advantages and different necessities, it is possible to use concrete hardener in Oil, Gas and petrochemical industry, Defense Industry, Steel making & Cast Ironing industries, Automobile making industries, Airplane & helicopter industries, Electronic / Electrical Industries, Power Stations, Paper making industries, Textile industries, Plastic making industries, Parking, Sidewalks, Malls, Outdoor levels, warehouses, workshops, production salons, loading platforms, discharge platforms and all surfaces which are subject to pressure tension, abrasion and shocks. ​​​​​​​

Minimum water to cement rate: 0.4
Maximum water to cement rate: 0.55
Suitable slump at concreting place: 70-100 mm
Maximum concrete air: %3
Minimum thickness of concrete: 75 mm
Minimum pressure resistance of concrete (for high traffic & loading surfaces): 30 N/mm2
 
Points:
If you need to use cement substitutes in the mixing design (such as microsilica, zeolite, etc.), it is recommended to use pre-prepared compounds such as POWER GEL.
It is seriously recommended to use reducing materials including in lubricants family of Zorlu Co. for reduction of W/C as well. The consuming quantity for covering one square meter is about 3 to 7kg of hardener.
 
Consumption method:
Upon the end of concreting and semi-dry of concrete surface (Not dry- Not wet), you may apply hardener. The physical condition of the concrete should be such that the foot does not sink into the concrete when walking, but the footprint can be seen on it. Note: Concrete parts should not be waterlogged.
 
 
According to the considered surface application, pour hardener powder on concrete sections for absorption of moisture.
Upon absorption which may change the powder color, immediately polish the concrete surface by a hand or electric trowel.
For finding a smooth & harmonized level with suitable resistance, you may polish the final layer by an electric (blade) trowel. For this purpose and after dry spraying of material, it may find necessary resistance for tolerating a person’s weight with a little sinking, then it is ready to apply blade trowel.
Like other concrete surfaces, the method and time of preparing this material exactly after performance are so much important which should be applied immediately as much as possible. After the finishing of troweling, start water spraying for preparing of hardened concrete.
For any performance in temperatures more than 30° C and warm/dry environments with windy condition, it is recommended to use Zorlu Curing Material for better processing of made surfaces.
