This paper presents the experimental results of the flow property of fresh polymer-modified mortars having cement/sand=1/3 (by mass) with varying water-cement ratio (W/C) and air content at the various polymer-cement ratios (P/C), using carboxylic styrene-acrylic ester co-polymer dispersions.
The flow property of the fresh polymer-modified mortar was affected by the P/C, W/C and air content, especially, the P/C had a marked effect on the flow property.
The experimental regression equation for calculation of the flow value is derived from P/C, W/C and the air content as the coefficient and constant. The physical meaning of the effect of each item in the equation on the flow property was explained by the author.
