Screed: components and cooking

If you want to make the floor covering ideal, you should certainly be careful about the possibility of making the right screed. Here we can say with considerable confidence that a very important factor in the formation of reliability and excellent quality is the correct preparation of the mixture.

Ordinary standard proportions of cement and sand should be within clear limits. No more than three parts of the sand are taken per part of the cement. We draw your attention to the fact that if you do not adhere to this proportionality, then you can get a mixture that will have a significant tendency to shed and the formation of cracks, that is, the floor screed will not be perfect.

If the mixture has a minimum amount of cement, then the floor will most likely not have the necessary indicators to resist the loads and strength. It is for this reason that the screed will very quickly become worthless.

It is very important that the proportions are actually determined perfectly. In this case, the sand is measured by clearly defined weight, cement – by packaging. In general, a fiber is also added to the mixture, which allows you to obtain higher reliability and strength of the mixture, but it can be added both when preparing the solution and directly at the construction site.

Please note that there are a fairly significant number of methods that are based on the use of other plasticizing components and galvanized or steel grid. Nevertheless, it is polypropylene fiber that can give us the highest indicators of the efficiency of use. In general, this material is the basis for a decrease in plastic shrinkage, and also helps to strengthen the screed.

When using this material, the risk of cracks and stratification decreases, the strength increases significantly and high indicators of abrasion appear. The durability and shock stability of the screed increases.

I would like to note that about a kilogram of polypropylene fiber is introduced on one cubic meter of prepared mixture for the manufacture of screed. In this case, alignment of the floor will be very effective, and through the use of a grout, you can get high indicators of the strength and density of the screed.

After the introduction of the fiber, it is best to mix the mixture in very detail to have priorities of the perfect combination of all components. If you strive to obtain high -quality indicators of the reliability of the finished screed, then the mixing process is best done on the basis of the use of specialized equipment. We draw your attention to the fact that in the case of preparing a mixture for screed it will not work to use a mixer with a free move.

The thing is that the material has a minimum amount of water, for this reason to bring it to the necessary consistency by means of the free course of equipment will be simply unrealistic. That is, it becomes clear that in this case it will require the use of a meshka with a forced principle of action. In general, the manufacture of screed, gypsum plaster, and many other construction mixtures are made precisely on the basis of the use of mixers with a forced mixing principle.

So you can achieve ideal indicators of mixing the construction mixture to the necessary consistency, and the dry screed will be just perfect. In the manufacture of the mixture for the formation of screed, it is also a very important point is the use of a clearly defined amount of water, which should be slightly so as not to spoil the mixture and enough to ensure that the cement-sand solution is priority to ideal strength.
