No construction industry is complete without concrete. This material is highly durable, reliable and durable, so no replacement has yet been found. However, even the most durable concrete structures deteriorate over time. And there can be a lot of reasons for the formation of cracks, chips and other defects. This is the influence of the environment and mechanical influences, violation of the technology of mixing the main elements of the solution, load, and the like.

To restore the original properties of the material, concrete repair mixtures are used.

Features of the

After the creation of mixtures for the reconstruction of concrete, the builders no longer needed to completely replace the deformed sections. Now, thanks to special repair substances, it is possible not to spend large sums and time on restoring the original parameters of the concrete system. With the help of restorative mixtures, the defective product gets an attractive appearance and returns to its original properties.

The composition of the repair joints is designed in such a way that the concrete base and the mixture itself reliably adhere to each other. After they have completely solidified, you do not have to worry that the updated system will soon become unusable. High-quality repair mixtures from well-known manufacturers do not need to be quickly replaced, since they differ in a number of positive properties.

Among them:

  • frost resistance;
  • resistance to sudden drops and rises in temperature;
  • vapor permeability;
  • long period of service;
  • high level of adhesion;
  • antiseptic abilities;
  • water repellent capabilities.

Indications for use

The repair mixture is used if a large number of cracks, potholes and other defects appear on the concrete surface, which are open by 0.3 mm or more. In addition, almost all concrete structures are characterized by increased dust formation, this fact is also an indicator for the use of a repair compound.

Concrete structures can be covered with voids, suffer from rust, and a variety of defects can form on them. All these points are the reason for the use of the reducing composition.

Classification

In most cases, repair mixtures are sold in the form of a powder, which must be diluted with water before use. Some manufacturers add certain components to their products to improve the properties of the concrete base.

Repair substances are classified according to their destination:

  1. for the regeneration of concrete systems that are under stress, for example, load-bearing building structures, beams, columns;
  2. for the reconstruction of concrete flooring;
  3. to protect reinforced concrete structures from rust.

In addition, there is a division into dry mixes and injection molding.

Dry mixes are used to recreate the original properties of concrete and to strengthen solid structures.

Resistance to the most severe frosts and high durability allow using these products for repairing systems that are regularly under the negative influence of natural phenomena and constant stress.

Due to such parameters as strength and endurance in conditions of high humidity, concrete waterproofing is often performed with restoring materials. The dry material is environmentally friendly, safe for human health, therefore it can be used for domestic purposes, for example, to restore the previous type of containers for supplying drinking water.

The last criterion determines the division of repair mixes into industrial and household ones.

Casting masses are used to fill cracks and small pits previously cleaned of dirt. They expand during pouring, reliably adhere to concrete, and practically do not shrink when solidified. Filling the resulting voids, the solution hermetically closes and seals the damaged area. Casting mixtures are used to restore horizontal planes.

According to the complexity of the initial composition, mixtures are distinguished:

  • monocomponent - cement compositions with large and small particles;
  • two-component - prepared using synthetic resins;
  • multicomponent - liquid polymer repair compounds.

The modern market also provides restorative compositions for concrete with limited operating conditions.

Fast-acting mixture for repairing concrete bases

The name itself suggests that such products dry out and harden quickly. As a rule, within 30 minutes after filling, work can be carried out using loading heavy equipment.

These types of mixtures are very helpful when it is necessary to make repairs as soon as possible. For example, in factory warehouses, where different goods are constantly moving, and downtime due to forced repairs will be a real disaster. If you need to repair the concrete structure as quickly as possible, but at the same time with high quality, then quick-acting mixtures are the best solution.

Shrink-free repair product

Shrinkage refers to deformations that occur as a result of a reduction in the amount of cement stone in a concrete solution. They are formed during the volatilization of water from the adhesive mixture, therefore, the more liquid is required for the mortar, the deeper the shrinkage will be.

A simple construction mixture shrinks up to 5 mm, which in the construction business is considered a rather large figure. Such shrinkage can provoke the appearance of shrinkage cracks.

To prevent early destruction of the concrete system, it is precisely non-shrinking repair material that is used.

Thixotropic mixture

This type of repair substance is specially designed for the repair of vertical surfaces and inclined walls. Due to its design features, it does not require the use of an auxiliary lathing.

The high viscosity of the substance does not allow it to spread outside the treated area.

Manufacturers

The modern market is distinguished by a wide range of different reducing compositions for concrete structures that have lost their original appearance and characteristics. They differ in composition, functionality, consumption, cost, quantity per package and, of course, the name of the manufacturer.

To date, several manufacturers are considered the most successful in terms of sales, and, therefore, the highest quality, in the opinion of consumers.

Domestic repair mix Emaco

It is used to improve the properties of concrete products that have minor damage. The constituent components of the company's dry mixes are: fine quartz, viscous polymer additives, non-toxic and absolutely safe for humans. The solution removes large and deep cracks from 2 mm to 2 cmformed on concrete foundations.

Emaco repair mortars are highly resistant to low temperatures, so they can remove flaws in concrete systems even in winter.

  • Tikstotropic mixtures are best suited for strengthening vertical surfaces. They have a thick consistency, adhere well to concrete, so they will firmly adhere to the walls.
  • Surface leveling mixtures must have high adhesion properties.
  • Important characteristics that you need to know before buying a repair mixture are:

    • solidification period - the smaller it is, the better;
    • material consumption - the instructions on the package usually indicate how much mixture is required to complete a specific task;
    • degree of protection against ultraviolet rays sun, frost and chemical effects;
    • shrinkage rate - there are non-shrinking repair mixtures on sale, it is better to buy them.
