Drying Shrinkage of High-Fluidity Polymer-Modified Mortar Using Redispersible Polymer Powder

재유화형 분말수지를 혼입한 고유동 폴리머 시멘트 모르타르의 건조수축

The effects of polymer-cement ratio, antifoamer content and shrinkage-reducing agent content on the setting time and drying shrinkage of high-fluidity polymer-modified mortars using redispersible polymer powder are examined. As a result, the setting time of the high-fluidity polymer-modified mortars using redispersible polymer powder tend to delayed with increasing polymer-cement ratio, regardless of the antifoamer conten,. Irrespective of the antifoamer content, the drying shrinkage of the high-fluidity polymer-modified mortars using redispersible polymer powder tend to decrease with increasing polymer-cement ratio and shrinkage-reducing agent content.
