When choosing a repair mix, the first thing we pay attention to is the compressive strength. To date, the average strength of repairers for horizontal surfaces is 40-65 MPa. But for some objects, for example, runways, railway tracks or bases of wind turbines, even such a high strength as 65 MPa may not be enough. What to do?
We offer you to get acquainted with the new product from the Turkish manufacturer Tekno – Teknogrout XX L. The material is specially designed for facilities where it is necessary to ensure maximum strength of the concrete structure, since the load on the surface can exceed hundreds of tons.
Teknogrout XXL is a high–strength cement-based repair mixture that does not shrink and has increased adhesion. The strength of the material is more than 90 N/mm2. By the way, in some tests, the compressive strength reached 130 N/mm2.
What are the advantages of Teknogrout XXL repair mix?
The main advantages of a high-strength repairman include:
- The permissible thickness of the application is greater than any other repair mixture (up to 150 mm in one layer).
- The compressive strength is more than 90 MPa.
Shrinkage – up to 0.30 mm/m.- Fast solidification: the mixture begins to set within 15 minutes after kneading.
- High tensile strength – from 2.0 N/mm2.
- Increased adhesion. It can be safely used on old concrete surfaces. But to get an even better effect on old concrete, you can apply a special cement mixture – Tekno AD, which increases the adhesion between old and new concrete surfaces.
- Gains strength in cold weather conditions (from 2 °C).
- Resistant to moisture
- Resistant to carbonation.
Where can I use the repair mixture Teknogrout XX L?
Teknogrout XX L material has been specially developed for repairing the bases of wind turbines. But in addition to this field of application, it is used:
- for the repair of railway tracks
- for the repair of aprons and runways
- for repair of warehouse premises
- to strengthen the joints of large reinforced concrete structures.
If you are still thinking about which repair mixture you should choose, we suggest you read the article "Recommendations for choosing a repairman", in which you will find many tips and recommendations for choosing a material.
