Concrete repair mixes
Concrete is the main material in the construction of buildings and structures. Its integrity and strength are the main guarantees of the reliability of the entire structure.But despite its strength characteristics, over time, under the influence of the destructive influence of the external environment, the degradation of the concrete structure occurs. Cracks, voids and other damages appear in it.
The reason for this may be:Shrinkage of the soil
- Incorrect design of the structure
- Incorrect production of concrete mix. A common mistake is incorrect proportions of sand and cement. Also, the reason may be an unsuitable brand of cement and incorrect kneading technology.
- Corrosion of concrete, which can be caused by: bacteria and fungi that develop on the surface of building structures and penetrate into the capillary-porous structure of concrete, thereby destroying it
- The influence of weather factors and improper care (after laying it was wetted and allowed to overheat, overdrying or freezing)
- Exposure to chemicals found in the composition of concrete and in the environment with which it interacts
Concrete is destroyed even with the observance of manufacturing technology and proper care. The reason for this may be a strong blow, heavy loads, negative environmental effects (gases, acid rain, sea water, etc.)
Signs of concrete destruction:Peeling surface .
- Occurs when the concrete is improperly prepared and dried.
- Cracks and crevices. They appear from excess loads on the structure and shrinkage of concrete at an early stage of its hardening.
- Biocorrosion of concrete (fungi, mold, algae).
- Rust streaks (a consequence of rebar corrosion).
Elimination of defectsNow there is a wide range of materials and tools on the market to combat various types of concrete damage.
The choice of funds depends on the specifics of the concrete structure and the type of damage. Breaking into the work on the elimination of defects on the concrete surface, first of all, it is necessary to identify and eliminate the cause of their occurrence. Then the surface must be treated with Tekno repair compounds. If defects have arisen on vertical concrete surfaces, repair mixtures Teknorep 200, Teknorep 300, Teknorep 300EX are used to eliminate them on horizontal ones – Teknogrout EX, Teknogrout 350, Teknogrout Rapid.
If there are water leaks in the concrete, they must be eliminated with a Teknoplug or Teknoplug Yildirim hydraulic seal.
Special attention should be paid to the reinforcement in concrete. Any industrial facility contains a lot of elements and structures made of metal, which can be subject to corrosion. All this comes from the negative effects of the environment and aggressive production factors. To protect the reinforcement in concrete, we recommend using a special cement corrosion inhibitor and an adhesion enhancer Tekno AD. This product has high adhesion to concrete and rebar, protects the rebar from moisture and is very easy to use.
