The effects of polymer-cement ratio, antifoamer agent content and shrinkage-reducing agent content on the drying shrinkage of polymer-modified mortars using redispersible polymer powder are examined. As a result, 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. Such a drying shrinkage development is due to the effect of reducing water from incorporation of EVA redispersible polymer powder and antifoamer agent.
