At the moment, it is difficult to surprise someone with the fact that there are special additives in concrete that can improve its technical characteristics. These include plasticizer for underfloor heating. When using certain additives, it is possible to obtain the necessary characteristics: high strength or low permeability, durability, increased resistance to frost, fast or slow set strength of the mixture, and so on. Thanks to these impurities, it is possible not only to generally make the properties of concrete better, but also to endow it with some specific characteristics that may be required in different situations. However, it is worth considering in more detail just a plasticizer for a warm floor.
This additive has proven itself perfectly, it has a stable composition and precise action, allows you to adjust the properties of concrete in a very wide range. Softener for underfloor heating provides a quick and very dynamic set of strength. Thanks to the active use of such additives, it is possible not only to achieve a significant increase in strength, but also to increase water resistance due to the water-reducing effect.
If you need to increase the spreadability and mobility of building mixtures intended for screed heating floors, it is necessary to use a plasticizer, since ordinary concrete is not suitable for these purposes. First of all, such an additive will increase
the compressive
strength , and also increase the elasticity of the screed. If you do not use a
plasticizer to screed the underfloor heating, then its layer above the pipes will exceed 50 millimeters, and so it is permissible that it is 30 mm. Using this mixture, you can make a solution of the following composition: half a ton of sand; half a centner of water; centner of cement M400; 7.7 liters of plasticizer.
The main effect of this supplement is as follows:
- increases the solubility of cement clinker;
- the additive interacts with the particles of cement, pushing them, that is, makes the mixture more plastic;
- the mixture becomes denser, while reducing the number of air pores and water;
- the formation of complex compounds with cement minerals can accelerate hardening, as well as increase the strength of cement;
- on the particles of cement is the formation of a waterproof layer, which leads to increased resistance to various aggressive influences.
Plasticizer for underfloor heating, the price of which is from 250 rubles per liter, is used very widely, not limited to floor insulation. It can also be used for floor slabs, bulk floors, industrial floors. The average time of complete hardening will be 25-30 days. It is necessary to store plasticizer for a warm floor at positive temperatures, stirring from time to time, if the storage period is very long. Adding to the solution should be done in compliance with the simplest safety rules, trying to protect hands and face.
