Current challenges in the building industry are related mostly to the preservation of virgin/natural materials, decreasing the environmental footprint, and increasing the reuse rate of disposed materials. This paper reflects current trends in the use of secondary raw materials of various industrial processes as sources for the production of alternative materials, for example, alkali-activated materials (AAM). Specifically, the paper deals with the description of the basic physical and mechanical properties of finely ground granulated blast furnace slag activated by waste alkali from cleaning processes in the glass industry. To provide more detailed insight into the material microstructure, scanning electron microscopy is employed. Obtained results refer to the capability to produce a material with a compressive strength of 21.7 MPa, which is less of a burden on the environment due to the use of by-products from industrial production. The introduced research line has great potential considering substantial benefits accompanied not only with the replacement of commercial alkali activator solution but also to decrease environmental and financial consequences of demanding waste alkalis disposal.
