Abstract

Amide-modified polycarboxylate superplasticizer (PCE) has shown many advantages compared with conventional polycarboxylate superplasticizer due to its unique molecular structure. In this study, we introduced three types of clay, montmorillonite, kaolinite and muscovite into cement and their influence on the dispersion ability of conventional PCE and amide-modified PCE was compared. It was found that conventional PCE is negatively affected by all three types of clay especially for montmorillonite where as amide-modified PCE was less affected. The concrete application performance showed that amide-modified PCE was more robust than conventional PCE when clay-bearing aggregate was utilized.
