The purpose of this study is to clarify the effect of the monomer ratio on properties of the polymer-modified mortars based on re-dispersible polymer powder, and to obtain basic data necessary to develop appropriate latexes for cement modifiers. This paper deals with the effects of monomer ratio on the typical properties of the polymer-modified mortars with re-dispersible polymer powder. The polymer-modified mortars using the re-dispersible polymer powder are prepared with different polymer-cement ratios, air contents, water-cement ratios, flexural and compressive strengths.
From the test results, the polymer-modified mortars using re-dispersible polymer powder can be recommended for practical applications. Their basic properties are greatly affected by the polymer-cement ratio rather than the polymer type, and are improved over un-modified mortar.
