MECHANICAL PROPERTIES OF EPOXY-MODIFIED MORTARS WITHOUT HARDENER

Abstract

In the production of conventional epoxy-modified mortars, the use of any hardener is indispensable. However, there is the fact that even without any hardener, the hardenering process of epoxy resin can proceed by the action of hydroxides in cement mortars. Epoxy-modified mortars without and with a hardener are prepared with various polymer-cement ratios, and tested for compressive, flexural and tensile behavior. As a result, the epoxy-modified mortars without the hardener have a larger strength and deformability than the mortars with the hardener at polymer-cement ratios of 20% or less.
