Environmental pollution is a major issue that we are dealing with at the moment. The reuse of industrial waste, which is used as raw materials in other industries such as the construction materials industry, is a beneficial way to reduce pollution. This is possible due to the physical, chemical, and mineralogical properties of industrial waste. Examples of industrial waste that can be used for obtaining new building materials are: fly ash, furnace slag, silica fume, and so on. These wastes were analysed in this study using the following techniques: SEM, XRD, and EDAX. After characterization, the wastes were used as additives in cement-based materials. The following properties of the obtained materials were tested: compression strength, flexural strength, adhesion to the substrate, and shrinkage testing. Based on the results of the tests, the percentages used as waste addition were chosen.
