Abstract (in english)
   Concrete is flexible construction materi al, which is utilized in various technologica l applications for underground structures and reinforcement of mine works (adits, tunnels etc.). In such applications, concrete has ma ny functions - static function, water-tightness, gas-tightne ss, resistance to action of aggressive waters as well as durability. In case of railroad and road tunnel constructions, there is an other important problem: influence of high temp eratures on concrete lining during wildfire. The paper focuses on analysis of behavior of cement composite material (concrete ) exposed to high temperatures. Several possibilities of increasing resistance of cement composites to high temperatures are proposed as well as recommendation fo r reduction of damage on structures exposed to high temperature.
