Abstract:Polycarboxylate based plasticizers (PCE) have been highly valued by the academia and concrete engineering because of there high water reducing rate and good strengthening effect. However, in the field of PCE research, although some achievements have been made, there is still much work to be done on the research of PCE mechanism, the development of new PCE products and the improvement of PCE application technology. In order to further promote the progress of PCE industry, combined with the actual needs of concrete engineering, six hot issues on the further research of PCE are put forward.
