• Epoxy mortars modified by PET glycolisate were obtained.
• Epoxy mortar was hardened using three different amino curing agents.
• Selected physico-mechanical properties of modified mortars were determined.
• The curing agent that allows the obtainment of the best composites was indicated.
• A significant impact of the type of curing agent was confirmed.
In the area of chemical applications in construction they are new materials, which do not have equivalents in nature. Polymers can be used to successfully replace traditional materials of the wood, metal or ceramics types. Among the polymers, one of the most important groups are epoxy resins, whose popularity stems from a combination of excellent mechanical and chemical properties. At the same time, the characteristics of epoxy resins are strongly dependent on the type and quantity of curing agent. The article presents the results of research on epoxy mortar modified with PET glycolisate, hardened by using three different amine curing agents. Characteristics such as flexural and compressive strength and water absorption were determined. The results were subjected to statistical analysis and compared, indicating the curing agent that allows the obtainment of a composite that is characterized by the highest values of the tested parameters.
