Whether and how many polymer particles will be adsorbed on the cement grain in the polymer-modified cement composites (PCC) is still a question. In this paper the possibility and the test method of adsorption of polymer particles on the cement grain were reviewed. A theoretical analysis on the principle of adsorption was discussed. It was then summarized that polymer particles will be adsorbed by the cement mainly due to electrostatic attract and the entropy effect. The zeta potential measurement based on the electroacoustic principle is a useful tool to study the adsorption of polymer, in combination with sedimentation of the polymer latex-modified cement with high water/cement (W/C) ratio quantitative evaluation of the adsorption is possible.
