Utilization of waste alkalis to alkaline activation blast furnace slag
Original language description
Alkaline activation of secondary raw materials, not only for industrial production, has recently come to the forefront of research. Alternative materials produced in this way often have a lower carbon footprint and are able to compete with conventional cement-based materials, which are a significant burden on the environment. Various alkali-activated precursors are being investigated in research, particularly using commercial activators, the production of which is a significant polluter of the environment. This work focuses on the use of waste alkali from the glass industry as a potential activator for the production of alkali-activated materials. The aim is to produce a material based on finely ground granulated blast furnace slag activated with the aforementioned alkalis and to describe the basic functional parameters. Parameters such as the mineralogical composition of the mixtures, the surface structure by electron microscopy, the compressive strength or the solidification process of the mixtures were investigated. An alternative material with a compressive strength of 25.4 MPa was produced. The solidification time of this material ranges from 2 to 7 h, depending on the molarity of the solution used. The research proves that it is possible to use waste activators to produce alkali-activated material with parameters like those of commonly used structural concretes of lower categories.
