What is the best repair mixture for concrete?

Concrete surfaces and structures have the qualities of durability and high strength, however, with prolonged use or significant loads, they appear damaged and cracked. In this case, a repair mixture for concrete will help. However, before acquiring it is important to consider the features and quality characteristics of each brand.

Characteristics of repair mixtures

The mixture intended for the restoration of concrete structures and surfaces must be resistant to frost, temperature changes. Among other things, it must have a high level of adhesion, as well as demonstrate longevity. The composition should have antiseptic properties and vapor tightness. After application to the surface, the mixture must be able to cope well with the effect of water.

Indications for the use of the repair mixture

The repair mixture for concrete is applied when there are a large number of potholes and defects on the base. Use such compositions when the cracks are opened by 0.3 millimeters or more. Quite often, concrete is characterized by increased dust formation, while also showing the use of a repair mixture. The structure can be covered with voids, corroded, it can be all kinds of defects. In all these cases, it is recommended to use a repair mixture.

Manufacturers of repair mixtures

The repair mixture for concrete "Emako" is made in Russia. It is used to restore concrete structures that have serious or minor damages. This compound can eliminate five different degrees of damage.

The first degree assumes the presence of shells, shrinkage cracks, and also contamination. The maximum depth of damage is 5 millimeters. To eliminate such errors, use a mixture of Emaco N 5100.

The second degree of damage involves flaking the surface and the presence of minor chips. In order to get rid of such shortcomings, the compositions of the Emaco N 900 and Emaco N 5200 grades should be used.

The third degree implies the occurrence of cracks in the range of 1-2 millimeters and rust. The maximum depth of damage is 40 millimeters. If you choose repair mortars for restoring concrete with such errors, it is best to purchase the Emaco S 488 PG, Emaco S 5400 and Emaco S 488 grades.

The fourth degree is the cracks, which are more than 0.2 millimeters. In this case, a bare armature may appear and carbonization may be noted. The maximum depth of damage is 10 cm. It is best to remove mixtures of Emaco T1100 TIX, Emaco S560FR or Emaco S 466 to eliminate such damage.

The most recent destruction belongs to the fifth degree. In this case, the reinforcement can be bared, on the surface there can be deep cracks. The depth of damage is greater than 20 cm. The Emaco Nanocrete AP will help protect against corrosion. If you decide to use repair compounds of the above brands, then you will have to pay from 13 to 26 dollars for 25 kg.

Repair mixtures brand "Birss"

Repair mixtures for the restoration of concrete are manufactured by the company "Birss", which is located in Russia. These compounds are intended for restoration of structures and concrete bases. If there is a need to cope with the damage of the first degree, then you can use the mix "Birsse 28", "Birss 29". Whereas with the second degree the compositions "Birss 30 C1" and "Birss 58 C1" will be able to handle.

This manufacturer has repair mixtures for all degrees of damage. The main advantages are resistance to salts, high adhesion, water resistance, frost resistance, density and elasticity, as well as wear resistance and stability before shrinkage. The price of such mixtures is much lower and equal to 6 dollars per 50 kg.

Features of repair mixtures "Bars"

The repair mixture for concrete "Bars" is convenient when applied and can be used for repairing horizontal and vertical surfaces. These compounds can be applied even to old concrete coatings. On the sale are mixtures of bulk and thixotropic type. The composition of the brand "Bars 102 V45" belongs to the last variety, it should be applied to the surface with a layer, the thickness of which varies from 2 to 4 cm. The composition contains non-shrinkage components as well as reinforcing fibers. The price compared to other mixtures is considered average and is equal to 13 dollars for 30 kg. If there is a need to eliminate water leaks in the construction of concrete, then you should use the cantilever "Bars 113", this mixture has additional qualities of strength and the ability to expand.

Features of repair mixtures "Ceresite"

The repair mix for concrete "Ceresite" is distributed in the market of building materials, perhaps, most of all. It has excellent properties for the restoration of all kinds of concrete surfaces and substrates. After application, the composition forms a non-stopper stopper, which is resistant to frost and water. It will reliably seal all cracks and leaks. To buy such a composition can be at a higher price than other mixtures, the price varies within 41 dollars for 25 kg. However, this mixture will be compensated by excellent quality.

Features of repair mixtures of ICBMs

In the assortment, you can find other varieties of compounds. For example, a repair mix for concrete MBR 500 is designed to repair structures that have defects. Such a composition can be stored for six months with a sufficiently wide temperature range, from -50 to +50 degrees. Considering the technical characteristics of this composition, it can be noted that it has different brands within the ICBM 300 - ICBM 700. Each of these mixtures can be stacked with the maximum thickness in one approach. For example, an ICBM 320 is applied at a thickness of 40 millimeters, while an ICBM of 700 is 20 millimeters thick. As an alternative solution in the latter case, the form can be used. After solidification of the ICBM, 700 acquires a density of 2350 kilograms per cubic meter. While the ICBM 300 demonstrates a density of between 2,100 grams per cubic meter.

Tips for choosing a concrete repair mix

The repair mixture for concrete should be selected depending on the type of defect, the expected load during operation, and the size of the damage. If there is a need to strengthen the base, then the most suitable option is the use of a deep penetrating primer mix. If you choose a repair mixture for concrete that should help to strengthen a vertical surface or a concrete structure, thixotropic compounds should be preferred. Such mixtures have a thick consistency and excellent adhesion qualities. This is due to the fact that they adhere well enough to the surface of the walls.

Conclusion

When leveling surfaces, use compounds that have good bonding properties. If there is a need to eliminate the cracks, then it is recommended to choose the compositions reinforced with fiber. Before buying, you need to pay attention to some characteristics of the composition, among them - the pour point, material consumption, and shrinkage size.
