A study of the effect of corrosive solutions on selected physical properties of modified epoxy mortars

• Investigated chemical resistance of epoxy mortars modified by PET glycolysate.
• The results obtained were shown as trend functions.
• Polymer mortars are excellent for use in the chemically aggressive environment.
• Application of plastic wastes allows making mortars of good chemical resistance.
• Investigated mortars are an innovative solution in construction materials.

A partial replacement of resin binder in epoxy mortars by PET waste based glycolyzates makes these building materials ecologically and economically interesting. The article presents the results of the first phase of research on epoxy mortars modified with poly(ethylene terephthalate) (PET) glycolyzates. Changes of some chosen mortar parameters (weight change, appearance of mortar specimens) due to the effect of the solutions of five aggressive media were monitored for twelve months. It was established that unlike ordinary cement mortars, the building composites that were obtained showed very good chemical corrosion resistance. The results of the investigation were presented as the trend function.
