Abstract

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