Flexible Concrete
In the Interfax-Ural at the end of August were held a press conference on the introduction of a new national standard for chemical additives in concrete, said "the Ural worker". Subject seemingly boring, purely technical, but because the concrete is the basic building materials, relating to many innovations. Produced annually worldwide 700-800 million m3 of concrete. Love it and Russian builders. Professor Saint-Petersburg Architectural Institute of Rudolf Sanzharovskyi noticed the fact that Ekaterinburg is actively using in situ concrete in the construction of high buildings. High, but not tall. In developed countries, with cast concrete buildings to construct a three hundred meters high. According to technical director for "Polimod" Nicholas Bashlykova, Moscow intends to build a complex of concrete buildings in the 30-35 floors, but it will unless supported by technological and normativn oy base.
Legislation, of course, Russia is. It is neither better nor worse than European, it is just different. Technical barriers to trade in construction products through Standards difference existed between European countries, but this year they switched to uniform standards, and national guests of all - Member States are in compliance with them.
Russia seeks uprovadytysya in the world of building design, construction products on the market, and therefore must "talk" with the parties on the same technical language. That is why the first guests in September introduced a new production of concrete, which greatly tightens the requirements for its quality, including with chemical additives. Chemical additives in concrete in the Russian construction practices used relatively recently. As the CEO, "Polyplast" Alexander Kovalev in Europe with chemical additives produced 80% concrete, but, for example, in Sverdlovsk region - about a quarter. Yes, and it is largely bla Godard that there is only one in the Urals and Siberia factory producing chemical additives, and half of its products used in the field, even a quarter - in the neighboring regions of the Urals, and the latter is exported. As the use of house hymdobavok Russian industry lags behind Europe in twenty years. Meanwhile hymdobavky deserve shanoblyvishe to a relationship. They can play a revolutionary role in the construction, including residential. When reducing the major components of concrete additives increase the ability to design, that is, its strength, frost resistance, resistance to corrosion. With its concrete steps with a heavy, ill-becomes a flexible, plastic material from which to build, as noted professor Robert Sanzharovskyi, thin and elegant spatial structure. Such concrete himself, without help from man drills, fills the formwork. If during the construction of dams Krasnoyarsk and Sayan-Shushenskoy HPS have been used hymdobavky how accelerated construction of a giant energy. A sarcophagus over Chernobyl emergency unit would be much stronger and did not allow cracks. In short, hymdobavky add new concrete quality that allows him to build a unique high-rise buildings that make what is builders can not do. Alexander Kovalev believes that demand for hymdobavky grow, and the introduction of a new tightening Guests manufacturers happy, because it puts a barrier in front of possible substitutes. While the manufacturers not to reinvent the wheel, get recipes and production technologies hymdobavok abroad, but in conjunction with the Moscow Institute of concrete created two new additions, which have not been on the market. Launching cooperation "Polyplast with USTU, UPI. At facilities LLC Polyplast-Ural-Sib "as reasonably believes his CEO Ilia Gorobets, now you can produce a wide range hymdobavok and increase their production in two or three times.
