Analysis of the Long-term Service Life of Coatings Based on Alkali-activated Matrices Exposed to Chemically Aggressive Environments

The paper deals with the possibility of using materials with an alkali-activated matrix for the secondary protection of reinforced concrete structures. Attention is primarily paid to the resistance of this type of coating to the effects of chemically aggressive environments. The long-term effect of selected types of aggressive environments on the coating based on alkali-activated substances was monitored using a set of physico-mechanical and physico-chemical tests. For comparison, a commercially produced epoxy coating with an increased resistance to the effects of chemically aggressive environments, as declared by its manufacturer, was subject to an analogous set of tests.
