Three epoxy resins and three types of glycidylether-based reactive diluents were used together in epoxy mortars. Six different amine-based hardeners, four aliphatic and two cycloaliphatic, were used in the mixtures. Test results showed that a hardener with higher functionality results in mortars with higher strength. The combination of diluent and hardener was found to affect both the compressive and flexural strengths of the mortars. The adhesion strengths of the mortars (to a sand-blasted concrete surface) were obtained by pull-off test. It was found that lactic and acetic acids have different levels of destruction in the epoxy mortars. (C) 2018 Elsevier Ltd. All rights reserved.
