How to protect reinforcement when restoring reinforced concrete structures

Reinforced concrete structures are constantly under conditions of increased stress and environmental impact, which is why they are subject to destruction over time. The repair of such structures is quite expensive and over time the cost of restoration can only grow. Because of this, it becomes clear that it is economically advantageous to increase initial financial investments in the manufacture of reinforced concrete structures or at the stage of their restoration.

A big disadvantage of reinforced concrete structures is the formation of corrosion on steel reinforcement, which acts as a significantly significant factor affecting the technical condition, safety, reliability and durability of the entire structure. That is why special attention should be paid to the protection of fittings, because the formation of corrosion on it can significantly shorten the service life of the entire building. It is possible to extend the life of the concrete block if protective measures are provided for the reinforcement against corrosion.

Corrosion formations appear on fittings most often due to the effects of atmospheric and chemical factors, which are caused by frequent and sudden changes in air temperature, as well as aggressive components of the atmosphere itself (chloride, carbonate, sulfate, etc.). The Tekno Ad corrosion inhibitor will be an effective solution to this problem.

Features and technology of Tekno Ad application

Tekno Ad is a special cement adhesive strengthener, which also acts as an effective inhibitor of corrosion formations on metal fittings.

This composition is used:

  • during the restoration and strengthening of reinforced concrete structures
  • in large engineering structures such as dams, tunnels, dams, etc.
  • to prevent the formation of corrosion on metal elements of reinforced concrete structures

Advantages of Tekno Ad:

  • The absence of toxic components in the composition
  • Simple application
  • Effective protection of metal fittings from moisture
  • High adhesive ability to rebar and concrete
  • Increased mechanical strength

 

 

The Tekno Ad cement amplifier is used according to the following technology. Previously, the work surface must be cleaned of everything that can interfere with the effective setting of the composition – it can be rust, dirt, oil, detergents, etc. Immediately before applying the composition, it is necessary to moisten the surface to be treated.

Mixing of the solution is carried out using a low-speed mixer. The mixture is added to a container with water, gradually stirring at low speeds for 5 minutes. After that, the solution is kept for 3 minutes, after which it is mixed again until smooth. The solution can be applied both with a brush and in a mechanized way, which is very important for large amounts of work. The finished solution should be used within an hour after cooking.
