Adhesion in Tension of Polymer-Modified Mortars with Blast-Furnace Slag and Fly ash

The purpose of this study is to evaluate the Adhesion in tension of cement mortar according to adding admixtures such as polymer dispersions, blast-furnace slag and fly ash. From the test results, the adhesion in tension is seriously affected by type of polymer compared with polymer-binder ratios and types of admixture. The maximum adhesion in tension of EVA- modified mortar is about 1.46 times, the cement mortar. It is apparent that the adhesion in tension of polymer-modified mortars according to adding two admixtures is much more improved irrespective of polymer-binder ratio.
