Dry construction mixtures are a group of dissimilar materials with specialized characteristics that are used for construction and repair work. In the form of dry mixtures, tile adhesives, masonry mortars, putties, plasters, hydro and thermal insulating compounds are produced. Immediately after mixing with water, the mixtures can be used according to their functional purpose, therefore they are very convenient for use in the conditions of the construction site.
The explosive growth of the market for building and finishing materials in the last decade was caused by the rapid growth of both construction and renovation works. Without touching on the reasons for this growth, we can say that the result was a variety of building materials. The accelerated pace of construction work required changes in the technology for their implementation. The emergence of ready-made building mixtures is the result of the development of these technologies.
The generalized name "dry building mixtures" speaks for itself - these are mixtures of the necessary components in the right proportion, which, when added with water, turn into a finished building or finishing material with the desired properties.
Only masonry mixes can be called exclusively building mixtures.
These include compositions intended for the preparation of both ordinary cement-sand mortar and special cement-based adhesive mortars, which are used to work with such modern materials as gas-foam concrete blocks, hollow partition blocks, groove-comb blocks, etc.
The most widely dry building mixtures are used in finishing works, where a one-time preparation of a large volume of the necessary solutions is not required.
A whole line of putty mixtures, despite all the variety of assortment, is intended only for leveling surfaces. But the surfaces are very different and for obtaining the most different end result. In this range, you can choose a mixture for leveling building facades - moisture-frost-resistant, for leveling concrete and plastered surfaces, both on a cement and gypsum base.
There are special putties for sealing and leveling the joints of gypsum plasterboards, putty mixtures for ceilings, for bathrooms, mixtures of various structures, colors, textured putties.
All the variety of this type of dry building mixtures cannot be described in one article. The huge range of putties is easily explained by the widest range of their application. As a special case of this kind, only plaster mixes can be distinguished, but their scope of use is limited to the initial stage of finishing work, therefore dry plaster mixes do not have such a variety and popularity as putty.
It is impossible to ignore the well-known everywhere "Adhesive for ceramic tiles". This type of dry mix is also very popular, which is a consequence of the popularity of ceramic tiles. The range of tile adhesives is limited to three types - basic (normal basic), reinforced (for working with natural stone tiles, for outdoor work), waterproof (for rooms with high humidity). The field of application of these mixtures is quite clear without explanation.
Recently, leveling compounds for the floor have become more and more popular, the purpose also directly follows from their name. The use of mixtures for leveling the floor allows you to obtain an ideal base for the subsequent installation of any floor covering - be it laminate floors, flooring, parquet or roll flooring. The special composition of some mixtures provides for the possibility of "self-leveling" the floor, which makes it possible, even without special skills and tools, to independently make even and solid bases.
Also in the series of dry building mixtures, various primers and insulation materials are very noticeable. They are not so well known among laymen, but this does not diminish their merits. These mixtures are used to restore old, crumbling surfaces, to provide waterproofing, to strengthen loose and porous surfaces. Remarkable properties and complex composition make mixtures of this class unique.
And another representative of mixtures for finishing works are special grouting materials for filling joints when finishing with the already mentioned ceramic tiles. All of them have increased moisture resistance, strength, have a wide range of colors in their assortment and are packed, as a rule, in small volumes.
It is clearly seen (even from such a brief and general overview) that the concept of "dry building mixtures" is very capacious, and it can be considered as a whole only on the basis of one common feature:
- these are ready-to-use special multicomponent mixtures with a very wide range of applications, for the use of which it is only necessary to dilute with water and mix thoroughly.
