Before finishing works, whether repairs or construction, you often have to deal with the alignment of the base. This is done with the help of various materials, so all screeds are divided into 3 main types. As a rule, the most attention is paid to the sexes, since they are subjected to the maximum load during the operation of buildings( structures).
In many cases it is preferable for them to build a semi-dry screed. Its difference from the so-called "wet" in that the proportion of water in the solution is significantly reduced + the fiber is introduced into the mixture.
The solution obtained by such a technology gives many advantages - shortening the availability of the layer, increasing its strength and a number of others. However, for large-scale works, it is not possible to perform all operations only manually, without a pneumatic blower. The main difficulty is the delivery of the solution from the place of preparation to the room in which the floor is prepared.
If it comes, for example, about a country house on several floors, then all this is spent quite a lot of time. And this is an increase in the cost of work. If the payment for the services of hired professionals is, as usual, done for the work done, the cost of renting the equipment is calculated on a daily basis. Even if the owner does everything on his own, then without a concrete mixer, few people do.
How to save on screed?
For the mechanization of the process of delivery of the solution to the "object" special units are used - concrete pumps and pneumatic blowers. The only difference is that the latter are able to prepare( and submit to the site of work) solutions with fillers of harder( hard) fractions. From the figure it is clear how and for what the air blower is used.
The specificity of its use depends mainly on the length of the sleeve on which the solution is transported. Some models can move it up to a distance of 180 m( horizontally) and up to a height of 45 floors.
Therefore, such equipment can be used not only to accelerate the alignment process, but also in the arrangement, for example, of the foundation. After all, the air compressors not only transport the "product", but also are able to prepare it from the loaded components. And the solutions can be very different. If we take into account the fact that several buildings are being built simultaneously during suburban construction, and many of the works are carried out in parallel, the expediency of application is obvious.
Cost of operation of the
- pneumatizer. Price of the products. It is quite high, so it is hardly advisable for the private sector to purchase such equipment. The simplest model will not cost less than 1 150 000 rubles .
- for rent. For the private sector, for example, when building a suburban structure in several floors, this option is preferable. For the rental will have to pay about 8 500 rub / day .If you plan your work in advance, prepare everything, allocate responsibilities, then, in principle, the costs justify themselves if you take into account the benefits. First of all, to save time.
