Today in the domestic market of dry construction mixtures (CAS), the situation has stabilized: its growth is 15-20% per year. Prospects for further development experts estimate as the most favorable - more and more construction companies moving to new technologies and begin its work to use the dry mixture. According directories, CAS - a group of supporting materials with specialized properties that are used in the management of construction and decoration. All the dry mixture can be divided into mortar, tile adhesives and porcelain, leveling compounds, adhesives, waterproofing and insulating compositions, repair and Improved sanitation compositions. These materials are in one group have in common is that they are made on the basis of binders with modifying additives, and in some cases - with the granular and reinforcing fillers and pigments. Tracks dry mixes are available in finished form, and after mixing with water, they can be used for other purposes. Pioneers Dry mix first appeared on the market only to Russia in 90 years of the last century. Before that all construction and finishing materials, such as assembly and mortar to cement binders, fillers, adhesives, lime and chalk paste, were prepared in the factories in the "wet" form - ready for use. At worst, they knead on-site work. The main disadvantage of plant mixtures was a limited shelf life - from several hours to a couple of solutions for months, putties and pastes. In the "field" mode of production is difficult to meet the necessary proportions, but because technology is making almost always broken - and, consequently, the quality fell. The first CAS, came on the market were manufactured in Poland, Finland and Germany: a Finnish stamps Vetonit, German Knauf plasters, etc. Their cost of domestic standards, was very high - due to high transport costs and low levels of competition . Within a few years after the arrival of "foreigners" in Russia have made their dry mix. In shops around the products of such brands as "Birss", "GLIMS", "Craps", "Bolars", "Eunice", "Miners". The market began to grow rapidly, adding about 40-50% per year. With builders like Today in our country's consumption of SSA per capita is between 2 to 3 kg per year, while in Germany the figure is 30 kg, and in France, Poland and Finland - 20 kg per year. The main consumers of dry mixes in Russia - is a construction and maintenance organizations - which accounted for 75% of sales. According to market participants, private traders in large numbers are not yet ready to consume CAS. The most popular type of dry construction mixtures - fillers, they bought more than 60% of consumers. About 50% use a mixture of plaster and universal. Slightly smaller proportion is adhesive for tiles, screed and grout for joints. Waterproofing and floors, a few years ago, not having much success in recent years are increasingly used builders. More than half of the market CAS traditionally concentrated in a few leading companies, representing brands Knauf, Vetonit, "Plitonit" and "Eunice": this market is still moderate market concentration. Experts suggest that the preferences of builders for grades mixtures have already been formed, and change them is not easy - so the prospects of rapid formation of new brands doubtful. In terms of breadth of the Urals market SSS can be considered rich: even in small towns offered at least 10-15 brands of products. Almost all major cities, in addition to foreign dealers, regional companies have their own manufacturers. Basically they sell their products in the same subject of the Federation, where the exception of the Permian plant Gipsopolimer, which supplies their mixtures on the market of Siberia. The selection marks CAS, which make Chelyabinsk consumers, is somewhat different from those in Russia on average. Moscow and foreign companies here, feel confident, but apart from "others" Knauf, "Henkel and Vetonit, large popular local brand" Master Kraft ". According to studies, approximately 40% of builders acquire materials "Plitonit", "Atlas" and "BIOPLAST. Also, well-proven local producer Brozex, making emphasis on materials for adhesive binders. Species diversity In the market of the Ural region offers many different types of CAS. This renders for exterior and interior applications: "drafts", leveling, finishing, water-resistant, waterproof, and erecting masonry mixes, putty, trowelling, rasshivochnye mixture and liquid self-leveling floors, and a variety of adhesive mixtures for stickers wallpaper, drywall, tile tiles and so on? d. More recently, there has appeared and is still considered an exotic mixture of refractory masonry stoves and fireplaces, hardener for concrete floors and an accelerator for hardening of concrete. All mixtures of type of binder divided into cement, cement-lime, lime, lime-gypsum and gypsum. As the filler can be used in building sand, crushed marble, ground limestone, mineral or organic fibers, metal fiber. Great influence on the properties of the mixture have a modifying agents. Today, they developed a great multitude, and in certain types of CAS can include more than a dozen different supplements, and some cover only a very small percentage of the volume. Additives accelerate or retard hardening, making a simpler ukladyvaemost, reduce the amount of water, increase the frost resistance and porosity. Thus, the inhibitors are required for concreting in hot weather and in some other cases, in particular for cementing wells. An air additive used to increase the frost resistance: due to the vacuum that concrete is able to grow - air, of course, involved in conventional mixing, but in insufficient quantities. Water-lowering additives, or plasticizers, can achieve a sufficient yield with less water - it leads to an increase in the strength of concrete. Need to be closer To select the necessary additions to the exact proportions is not easy, but it depends on what the final result will be a mixture. It additives make it attractive for a particular type of work; depends on them whether selling brand. But knowing the intricacies "recipe" dry mix little, experts say, need to adapt it to local raw materials and to test for compatibility with other materials used in construction. To be closer to the consumer with its features, companies from other regions, and even international, open in the Urals region of their
