Many types of formwork used in modern construction of concrete and reinforced concrete structures have special fasteners that remain in the poured concrete for a while. After removing the formwork and removing the fasteners, holes remain in the concrete structure that need to be sealed for waterproofing. Today we will tell you about a mixture with which you can quickly and efficiently repair voids in concrete — Teknorep 200.
What is Teknorep 200 repair mix?
Teknorep 200 is a cement—based repair thin-layer mixture reinforced with polymer fibers. The material has a wide scope of application, namely, it is suitable for filling voids left after the removal of the formwork during the construction of concrete structures, is used in minor repairs to obtain a smoother plane, is also used in the restoration and repair of any mineral surfaces, sealing cracks in engineering structures such as highways, dams, metro, mines..
The size of the granules is 0.700 mm. Teknorep 200 can be applied in a layer from 3 to 30 mm. The lifetime of the finished solution is ≥ 45 minutes. It is also worth paying attention to the high strength of the substance: the compressive strength is > 25 N/mm2, the adhesion strength with concrete is > 1.0 N/mm2. Shrinkage of the mixture > 0.8 N/mm2, density 2.05 kg/l.
What are the advantages of Teknorep 200?
The main advantages of this repair composition include:
- the possibility of applying a thin layer from 3 to 30 mm
- safety, non-toxicity of the mixture
- resistance to freezing and thawing
- Teknorep 200 does not cause corrosion
- easy operation.
How to use the repair mixture for sealing holes after removing the formwork?
The treated surface is cleaned of dirt, soil, oils or other contaminants.
In order to increase adhesion, it is recommended to use the Tekno AD corrosion inhibitor.
- The mixture is mixed with water in a clean container using a low-speed mixer (up to 500 rpm) according to the instructions. Please note: do not add water to the already prepared solution.
- It is necessary to apply the mixture with a spatula in a uniform layer. If there is a need to apply a layer thicker than 30 mm, the work should be carried out in several stages.
- After the end of application, the surface should be covered from direct sunlight, wind, exposure to low temperatures.
In conclusion, we note that the use of this repair mixture is very simple and does not require special skills or special tools from the master.
