Abstract:Converter slag is a metallurgical waste material for which there are utilisation problems. The phase composition of the material includes, beside the phases which are not reactive, mineral phases typical for portland clinker -tricalcium silicate (C3S), dicalcium silicate (C2S) and calcium oxide are always present in the converter slag. The authors have found that special preparation of the converter slag can strongly influence the durability of the concretes containing this material. The results concerning the resistance of the mortars containing converter slag to the corrosive solutions are presented. Microstructure of the mortars (SEM) has been analysed. Very low porosity and extremely low water permeability of the samples containing converter slag are the most important reasons for the high chemical resistance of this material.
