Original Abstract

Currently, we are carrying out several repairs to concrete structures that are permanently exposed to chemically aggressive environments and the effects of temperature and cyclic mechanical stress. It is therefore necessary to develop a highly resistant patching composite that would return the damaged objects to their original state or improve resistance to external attack. In this paper, results of the research, in which monitoring of the temperature was performed and chemical resistance of the polymer composites of repair, specifically with the epoxy matrix and a different type of filler, is presented. As a filler, we use secondary raw materials that are currently produced largely as a by-product of industrial production in the Czech Republic and abroad. It has been found that the type of filler used has not an impact on temperature resistance. but in chemical resistance plays a considerable role also used filler. The microstructure was also monitored before and after chemical stress.
