Graduate student of the Siberian Federal University, Coordinator of the Council of Young Scientists SFU Lyudmila Fatkulina-Yaskova proposed the idea of insulation of external walls of buildings with energy efficient aggregates.

The uniqueness of the development, according to the author of the project, that the aggregate in the interior wall structure works as a mini battery, that is, collects and retains heat inside. Such wall structures have the same strength characteristics as the lightweight concrete, but does not require additional insulation, whereby it is possible to reduce construction costs by 15-25%.

"Traditional building materials, widely used today in building envelopes have a low heat capacity, so the use of special materials with high specific heat will increase the energy efficiency of building envelopes and structures. This is very important in our Siberian conditions, "- said Ludmila. 

As fillers young scientist suggests using pellets with a diameter of 15-35 mm, consisting of a dense core (high-density concrete, clay, etc.) and heat-insulating sheath. As the latter may be virtually all of the existing building insulation materials: ecowool, polystyrene foam, mineral wool, foam glass and others.

Now the young inventor performs the necessary calculations, determine the optimal size depending on the materials used. "We choose this ratio core and shell insulation to aggregate had the same densities as the concrete in which it is placed, so that later could be a uniform enclosures" — said Lyudmila. This filler can be used in monolithic housing construction and in the manufacture of prefabricated products. From being used as a coating material directly related production technology and, in fact, cost. For example, when using insulation material ecowool costs will be minimal.

In Russian counterparts invention Ludmila does not exist. "For overseas use a spacer with the nucleus of the insulating sheath, but it works in a fundamentally different way. Pellets with a diameter less than 0.5 mm are made from polymeric materials and are used for conventional external insulation enclosing structures. In Russia it has been applied only as a surface warming of walls in the form of thermal paint ", — she said.

The scientific management of the project carries SFU Professor, Doctor of Technical Sciences Rashid Nazirs.

Earlier, Lyudmila Fatkulina-Yaskova participated in the start-ring battle innovative projects and business ideas among students and graduate students of SFU. Her project won in the category "Best Business Idea".
