Gasification in entrained flow reactors is now one of the most dynamically developed technologies of thermal conversion of coal. The basic, solid by-product of this process is slag, and in some cases also fly ash. In Poland, so far there have been no examples of industrial application of coal gasification. However, the high popularity of such systems in the world indicates the possibility of the appearance in Poland in the future, along with by-products of gasification. To pre-determine the possible future directions of management of this type of material, slag from coal gasification in foreign installation was obtained and tested. This article discusses the possibility of using slag from gasification of coal as a component of concrete and binding mixtures. The mechanical properties of such composites were tested because of the different content of the slag, the type of cement used, and the seasoning time.
