ABSTRACT

     The aim of this work is to analyse the chemical resistance of epoxy and polyester concretes when exposed to acids and salts. The chemical resistance is evaluated through the variation of bending strength and variation of mass, after exposure in acid and salted solutions, for various periods of time.

     Aqueous solutions of sulphuric acid and sodium chloride were chosen as test solutions. The increasing use of polymer concrete structures near seawater and residual waters is the main motivation for this research work.
