Development Brest scientists: eco house linen

That just does not make today flax. Butter. Fabric, including imitation of jeans. Included in the bezdrevesnoy fiber paper used for currency production. Ceases to be a headache and linen waste that "work" in the fuel, insulation boards, papers, in growing mushrooms and vegetables. And thanks to our scientists to fire flax recently enriched formula construction material used for the construction of buildings.

Brest residents, using evidence-based approach, thinking about the creation of eco about three years ago. Options? Rational use of disposable exhaustible fossil resources, subject to the technical requirements for housing. Another criterion - to a hundred years we have not had a headache like today disposed of know-how. The choice fell on the waste from the production of flax.

- Materials based on organic fillers scientists and experts are developing for a long time - continues to head of the department of technology of concrete and building materials BrGTU, Ph.D., Professor Victor Tour. - However, be included in the organic components, such as a fire flax, sawdust, straw, is difficult. Organics is not used with the cement system, because it does not allow to harden binder.

But make wall material derived from the use of flax fires, be durable and energy efficient - sounded tempting

. A year later, the test solution was found in lime, which is neutral to the organics, but it has other mechanisms of hardening. However, scientists lay in wait another test: it was necessary to make lime gain strength like cement. Development Brest scientists completely ready for mass use

- Lime hardens as a result of carbonization, ie the absorption of carbon dioxide from the environment - reveals details of his dissertation research senior lecturer in technology of concrete and building materials BrGTU Alexander Picula. - In a natural environment, this slow process is sometimes delayed for years. Accelerates its impact temperature and pressure, which, however, increase the cost of technology. We managed to find a cheap mineral components that modify the binding and form a reliable chemical compounds.

In the research laboratory of the University say this decision is applied for the first time in the world. And the development is completely ready for mass use: made laboratory test cycle, there is the technological regulations for production. Testing properties (ranging from strength and finishing with thermo-physical) showed that material competes with brickwork and wood

. How are going to build?

Brest scientists suggest several options. First, based on flax fires material can fill the cavity in the wooden frame. Secondly, it is possible to produce products of regular shape in the factory. Associate Professor of technology of concrete and building materials BrGTU Tatiana Shalobyta evaluates invention:

- "Linen" is no substitute for building material industry brick and technologies that are currently used in large-scale construction. It is good for individual orders: environmentally friendly, low-power house will successfully solve the waste disposal problem.

"The beauty of this business is - is intriguing Victor Tour - that you are able to make themselves a building material. We wish to give at all the technological instructions. " How confident? From the history! It turns out that at the beginning of the last century in our country, many rural houses erected on a similar principle. With only one difference: the fire flax mixed with clay and straw. Protects the wall from rain and sun plaster: mixed clay, lime and sand. The main problem of such houses were hens that hatch in the bottom of the home of lime and sand.

They say that new - it is well forgotten old. Let this postulate known to make a modest addition: new - is well forgotten and always research the old rethought.
