Resin composites with high chemical resistance for application in civil engineering

Abstract

The durability of building materials may be defined as a set of predesigned characteristics which the material preserves during possibly the longest period of use. Presently this is one of the basic criteria which decide about the choice of the appropriate material for building constructions. Contact with corrosion-inducing factors causes building materials to deteriorate and shortens their service life. The article presents initial results of research into epoxide mortars modified with glycolysates based on poly(ethylene terephthalate) waste. The possibility of the application of thus chemical resistance upgraded mortars was discussed. The weight changes of the mortar samples after their exposure to five chosen corrosion-inducing media were found. The results obtained were shown as trend functions illustrating the weight changes of each sample with respect to the time of their exposure to the particular aggressive solution.
