Originální abstrakt

The research presented in this paper is aimed at studying the properties of composites designed for reinforced concrete structures, which can be expected to have an increased risk of fire, i.e. shock to extreme temperatures. Two recipes were developed compositions based on polymer-cement matrix and porous filler. These materials were subjected to cyclic freezing and thawing in combination with the water. From the viewpoint of term, durability characteristics were observed both after 50 and 100 cycles. At this stage, the research has not considered the impact of increased humidity. After testing the frost resistance thus specimen were dried. Then thermal shock stress followed at temperatures of 400, 600 and 1000°C. Cooling of specimen was carried out with controlled gradual temperature decrease.
