Concrete is a building material that is used in a variety of fields and, depending on the scope of its operation, it is necessary to choose the right materials for its hardening and repair. Hardeners are various varnishes for concrete, impregnations, toppings and other materials, and special mixtures of increased strength based on cement are used for repairs.
In this article we will analyze how to choose the right material for concrete repair.
How to choose the right material for concrete repair?
When choosing a material for concrete repair, the following points should be taken into account:
- Type of concrete or reinforced concrete structure;
- Location of damage on the surface of the structure;
- Degree of concrete damage;
- Damage size including depth and width of damage;
- Intensity of operation of a concrete or reinforced concrete structure;
- Climatic conditions under which the structure is operated;
- All external factors to which the repair material must be resistant;
- The chemical environment of the structure.
Depending on the above points, we determine what strength the repair material should be, what modulus of elasticity it should correspond to, what external factors it should be resistant to, and so on.
Below are some examples of the choice of repair material.
Repair of concrete in the warehouse
When repairing a concrete surface in a warehouse, it is important not to stop work for several days, but to quickly eliminate defects. To do this, you should use a quick-setting repair compound, which in 1-2 hours will withstand the weight of a full loader. Such a composition is Teknogrout Rapid, which begins to set within 5 minutes after pouring, and after 1 hour you can safely arrive with a loader with products.
But it should be borne in mind that this material cannot be poured over large areas for repair, since it is not elastic.
Bridge concrete repair
When choosing a material for repairing a reinforced concrete bridge, it is necessary to take into account moisture resistance and resistance to corrosion on reinforcement and concrete. If it is necessary to repair vertical concrete surfaces, we recommend paying attention to Teknorep 300 EX - an elastic high-strength repair compound resistant to water, sulfates, chlorine, which prevents the formation of corrosion.
Repair of a concrete well
When damage is formed in a concrete well, it is recommended to use a special fast-acting repair compound that will cope with the hole formed in 1-2 minutes. This is Teknoplug, which is characterized by high adhesion to the surface and resistance to various mechanical influences.
