| Abstract |
The purpose of this study is to clarify the effect of glass transition temperature(Tg) on properties of the polymer-modified mortars based on acrylic latexes, and to obtain basic data necessary to develop appropriate latexes for cement modifiers. This paper deals with the effects of glass transition temperature on the typical properties of the polymer-modified mortars with acrylic latexes. The polymer-modified mortars using the acrylic latexes mixed with various glass transition temperature are prepared with different polymer-cement ratios, and tested for flexural and compressive strengths, water absorption, chloride-ion penetration and carbonation depth.
From the test results, the polymer-modified mortars using acrylic latexes with the mix proportions of various glass transition temperatures can be recommended for practical applications. The properties of strength are increased with an increase in the glass transition temperatures. The water absorption, chloride ion penetration depth and carbonation depth of polymer-modified mortar with high glass transition temperature are lowest. However, they are greatly affected by the polymer-cement ratio rather than the glass transition temperature. |
