We improve the quality of concrete solution: plasticizer for screed

Plasticizers are surface-activesubstances (or briefly surfactants), which are intended to be added to dry building mixtures to improve certain properties. Most often they are used when laying the screed on the floor, including when installing the system "warm floor". Surfactants have a special property, when added to the solution of the substance gives it a special fluidity and plasticity, so that the mixture lays down more easily and uniformly on the surface. In general, the plasticizer for screed increases the quality of the solution.

Increasing the plasticity of the solution leads toimprovement of other parameters of the mixture. In particular, due to a good distribution over the surface, material consumption is significantly reduced. The time taken to complete the work with the solution is also reduced. And after the screed hardens, it acquires high strength, good density, resistance to loads. At the same time, the hardening is reduced by about 2 days.

Currently, there is a wide range ofdifferent types of plasticizers, which give the solution these or other properties, some shops can provide everything from self-leveling mixtures for floors to nail polish. Therefore, it is necessary to determine the necessary parameters when choosing an additive. Maybe this increase in frost resistance, it may be necessary to accelerate the time of solidification.

Especially it is necessary to use a plasticizerfor screed under warm floors. This is due to the fact that it must be ductile, do not crack under the influence of high temperatures, withstand significant loads, provide reliable protection of equipment. It is these properties have a screed made of a solution of concrete with the addition of a plasticizer. In addition, the service life is also increased.

According to its condition, the plasticizer for the screedis divided into liquid and powder species. Surfactants in dry form must first be diluted with water in the correct proportion (should be indicated on the package), and only after that add small amounts in the cement solution. The mixture must be thoroughly mixed. Usually the average consumption of plasticizer is about 0,15-0,2 liters per 50 kg of dry cement-sand composition. At work it is necessary to take into account that the temperature of air should not be below +5 degrees.

The liquid plasticizer for the screed is already sold in ready-made form and is added directly to the solution in the required proportions.

Also plasticizer for screed can be inthe form of polyamide reinforcing fibers and in antifreeze additives. Each of the individual species gives the solution certain indicators, improving its quality.

With all its advantages plasticizers to thatthey are an environmentally friendly substance, absolutely non-toxic, do not cause corrosion on metals, have a neutral smell. The production and cost of surfactants depends on characteristics, consumption. It should be noted that the cheaper the material, the more likely its consumption is. Therefore, savings in this case can not always be effective.
