“…The effect of polymer dispersions on the hydration of Portland cement has been well disclosed from previous studies [13][14][15][16][17][18][19][20]. Generally, the addition of polymer dispersions would retard the hydration of ordinary Portland cement (OPC) [20][21][22][23][24][25][26][27][28][29][30], and this retardation effect becomes much more significant when the bigger polymer content was dosed [31,32].…”

The influence of three polymer dispersions [styrene-butadiene copolymer (SB), styrene-acrylic ester copolymer (SA) and polyacrylic ester (PA)] on the hydration of calcium sulfoaluminate (CSA) cement within 72 h was investigated by using isothermal conduction calorimetry, X-ray diffraction analysis and thermal gravimetric analysis. The results indicate that these three polymer dispersions perform different influences on the hydration heat flow of CSA cement during different periods, they all postpone the occurrence time of the maxima peaks, and its extent is mainly dependent on the addition amount. Polymer dispersions manifest great retardation on the initial hydration of CSA cement, and the effect is much more significant within 1 h. In this stage, the generation of ettringite is strongly delayed; however, the formation of ettringite is accelerated by these polymer dispersions at and after 2 h. Among these three polymer dispersions, PA demonstrates the highest acceleration effect on the hydration degree.
