Shrinkage of concrete: in search of the strength of structures

Shrinkage - the main disadvantage of concrete

from capillaries formed stone is gradually disappearing all the moisture, because of the relatively low strength of the composition of hardening the surface can not withstand the voltage and starts to deform.To solidification process material passes quickly and correctly, without the formation of cracks unnecessary, experts spend a lot of preventive procedures, special formulations used for the treatment of concrete and added to the liquid base impurity.

latter option also allows to increase the strength of concrete, its durability, and hence the life of the entire structure.At the moment, there are several options explaining the reasons for the shrinkage.You can not exactly say why concrete is deformed in a particular case, as a rule, there are several factors that affect the condition of the material.

Finding concrete solutions

shrinkage problems First of all, the process begins to take place due to a chemical reaction that occurs when water and cement in contact with air.However, these components are responsible for the strength of the solidified structure.Due to the swelling of the initial design value mixture increases slightly, but these changes are quite noticeable in a large area.

In order to carry out some parts bonding and concrete, it is necessary to use concrete sealant.Designed with all the features of the material, it does its job well.But to date, experts were able to develop a non-shrink concrete, it can be obtained by adding special additives that affect the density of the material prior to compression.

use of this composition makes it possible to reduce the losses brought by the effects of shrinkage, and reduces material consumption, which is especially important in large buildings.However, if in the process failed to get away, sealant for joints in concrete help to solve small problems.

stringing concrete can be used for construction purposes, when a high risk of damage to the structure.

In many countries, the addition of specific products is considered a mandatory procedure in the preparation of material to use.However, most often, this option is used during repair of ready-made designs, the composition allows to fill the gap without fear of damage to the main structure.

Such compositions are essential for the repair of the roadway, construction of bridges, airfields.-quality non-shrinking concrete - to restore the normal state of the structure in a few days.

How to minimize shrinkage?

to shrinkage is reduced to a minimum and the work was completed on time, experts recommend the use of special mixtures are also suitable version of the application of concrete with a lower proportion of sand.Depending on whether the work was carried out before or builders are at the stage of preparation of the mixtures, it selected the most suitable way of reducing shrinkage to a minimum.

For quality sealing of concrete is carried out using special tools that are applied to the frozen structure.Careful maintenance of concrete, complying with all the requirements for its operation and filling helps to get rid of unpleasant consequences, making the design more compact, reliable.
