METHOD FOR ARRANGEMENT OF ADHESION LAYER OF SPORTS FACILITIES ICE MASSIF Russian patent published in 2010 - IPC F25C3/02 A61C19/10 

FIELD: construction.

SUBSTANCE: method for arrangement of adhesion layer of sports facilities ice massif includes preparation of concrete board by means of its preliminary soaking under layer of water for at least 56 hours while temperature on its surface is lowered from 15.0°C to 0.5°C for complete air displacement from porous part of concrete and further mechanical rubbing of water into concrete surface by take-in squeegees of floor-washing machines. Process of rubbing is started together with the beginning of water crystallisation in near-surface layer of previously soaked board as temperature on concrete board surface reaches around +0.5°C, and water rubbing is continued after temperature on its surface drops below 0°C to form a solid mirror-like layer of ice on its surface at the temperature from minus 3°C to minus 4°C, and then adhesion layer is formed by application of water with high pressure washing devices till thickness of 1.5-2 mm is achieved.

EFFECT: application of this method makes it possible to provide for integrity, high adhesion properties of ice massif in zone of contact with concrete base, does not allow for cracking and flaking of lower layers of ice massif in process of operation.
