Originální abstrakt

Concrete is flexible construction material, which can be used by various technological applications for underground structures and reinforcement of mine works (adits and tunnels). In such applications, concrete has many functions – static function, water-tightness is often required as well as gas-tightness and resistance to action of aggressive waters or durability. In railroad and road tunnels construction there is one important problem – influence of high temperatures on concrete lining during wildfire. The paper focuses on analysis of behavior of cement composite materials (concrete) exposed to high temperatures. Several possibilities of increasing resistance of cement composites to high temperatures are proposed as well as recommendation for reduction of damage on structures exposed to high temperature.

Klíčová slova
