Title: Strength Losses of Polymer-Modified Concretes Under Wet Conditions

Abstract:Polymer-modified concretes were subjected to four different curing methods to see the effects of various moisture conditions on their strength developments. Three epoxies and one latex were included in the investigation. One test series was prepared with each polymer and was then repeated with the addition of a chloride-free accelerator. The strength results were compared to strengths of concretes of the same composition but without polymer. The comparison shows that wet conditions do reduce the compressive strengths of polymer-modified concretes, the magnitude of which is greatly influenced by the quality of polymer used. These strength reductions, however, can be counterbalanced by a suitable accelerator.
