Tekno AD is a special cement mixture that increases the adhesion between old concrete surfaces and new ones. Contains corrosion inhibitors and microsilicon.

Application

Tekno AD is used in the restoration of reinforced concrete structures and elements, bridges, overpasses, ramps, columns, retaining walls, water tanks and other infrastructure objects of long-term operation or due to destruction from corrosion processes and/or exposure to mechanical loads.

Features / Advantages

  • High strength
  • High adhesion to concrete and metal
  • Vapor permeable
  • Frost - resistant
  • Waterproof
  • Easy to use

The size of the filler granules < 1 mm
Flexural strength (TS EN 196-1) > 8,0 N/mm2
Adhesive strength with concrete  > 2,0 N/mm2
Compressive strength (TS EN 196-1) > 65,0 N/mm2

Foundation quality / preliminary preparation

Concrete:

The concrete surface must be thoroughly cleaned of weak parts, residues of any foreign materials, dirt, dust and other substances that can reduce the adhesion of the material.

Steel reinforcement:
Clean reinforcing bars from rust, concrete residues, dust and other substances that may reduce adhesion or contribute to corrosion.

Preparation of the working solution

Pour 3.5 - 4 liters of clean water into a clean container, gradually add the contents of a 20-kilogram bag, while stirring with a low-speed mixer for 5 minutes until a homogeneous solution without lumps is obtained. After mixing, leave the solution for 3 minutes and mix again before applying. You need to use a mixer with a maximum speed of 500 rpm.

Application

Priming of concrete, application of an adhesive layer:

The base must be thoroughly moistened with water two hours before applying Tekno AD. Keep the surface moist, but not wet. Excess water must be removed before applying the material. It is necessary to apply the working solution to the prepared base with a roller, brush or automatic sprayer in a thin layer until all the pores and voids are leveled and filled.

Protection of fittings from corrosion:

It is necessary to apply the first layer of the working solution with a thickness of 1 mm to the prepared base with a brush or an automatic sprayer in a thin layer until the reinforcement is completely covered. After hardening the first layer, apply a second layer with a thickness of about 1 mm. The repair solution should be applied only after the Tekno AD adhesive layer has dried.

We recommend using Teknorep series thixotropic repair mixes for vertical surfaces, and Teknogrout series self–leveling repair mixes for horizontal surfaces.

Limitation

  • Do not add other components to the solution
  • Do not add water to the working solution that has started to set
  • Protect the surface from the effects of adverse weather conditions and ambient temperatures below 5 °C and above 35 °C immediately after application.
  • Clean the equipment immediately after use.
  • May cause skin irritation, use protective gloves, goggles and masks while working.

1. What does corrosion inhibitor mean?

A corrosion inhibitor is a special cement-based mixture that increases adhesion between old and new concrete surfaces.

2. What is a corrosion inhibitor for?

A corrosion inhibitor is needed to prevent reinforcement corrosion, to repair and strengthen concrete surfaces, to increase the adhesion of concrete surfaces.

3. How does the corrosion inhibitor work?

The corrosion inhibitor is used in 2 cases: 
1. during repair work: covers bare reinforcement, protecting it from corrosion and ensuring good adhesion of the repair mixture to the reinforcement and concrete at the repair site;
2. when laying a new concrete mix on the old one: the material provides a reliable and durable adhesion of the two surfaces

4. What is the inhibitory effect?

Inhibitory effect means the suppression of the activity of substances, for example, that lead to corrosion of fittings. 

5. What are the corrosion inhibitors?

Corrosion inhibitors for the composition are divided into organic, inorganic and volatile, for the sphere of influence – neutral, acidic and alkaline, for the mechanism of action – anodic, cathodic and mixed.

6. What are corrosion inhibitors examples?

Tekno AD material is considered an excellent example of a corrosion inhibitor. It is easy to work, non-toxic, increases the water resistance of concrete, protects the reinforcement from moisture

and has high mechanical strength.

7. How much does the inhibitor cost?

The average cost of a corrosion inhibitor, for example, Tekno AD – 31 UAH per 1 kg. You can order or consult at the number 0800 307 050.
