The Effect of Curing condition on Adhesion in Tension of Polymer-Modified Mortars

양생존건이 폴리머 시멘트 모르터의 접착강도에 미치는 영향

The purpose of this study is to evaluate the effect of curing conditions on adhesion in tension of polymer-modified mortar to cement mortar substrate in comparision with ordinary cement mortar. The polymer-modifies mortars using two polymer dispersions and a redispersible polymer power are prepared with various polymer-cement ratios, and tested for the adhesion in tension of the specimens subjected to five curing conditions. From the test results, the adhesion in tension of polymer-modified mortars tends to increase with increasing polymer-cement ratio irrespective of the polymer types and curing conditions. It is apparent that adhesion in tension of polymer-modified mortars is considerably influenced by curing conditions.
