Synthesis, characterization and performance of a polycarboxylate superplasticizer with amide structure

- Amide-PCE was synthesized successfully and the optimal conditions were determined.
- The structure of amide-PCE and its sufficient amidation reaction were confirmed.
- Amide-PCE has better application performance than the conventional PCE in concrete.
- The dispersion mechanism of amide-PCE in cement-water system was illustrated.
- It can provide electrostatic repulsion, steric hindrance, complex and lubrication.
