ABSTRACT
One of the reasons for the use of waste materials is the decreasing amount of suitable non
renewable raw materials for the production of building materials m some areas. This paper describes the issue of the utilization of industrial waste materials, namely waste foundry sand and blast furnace slag as fillers for epoxy resin-based repair materials for concrete structures. These repair materials are intended to be used for reinforced concrete structures. The most important contribution of using these materials is from the point of view of the environment. Waste materials save natural sources, which could be spared for more appropriate use. Also the use of waste materials reduces demands on the environment.
