The dispersion ability of polycarboxylate ether (PCE) in fresh concrete is much impeded by clay impurities. To improve the dispersion of PCE in the clay-contained concrete, lignin-based polyoxy-ethylene ether (PEG-grafted-lignin) was synthesized through polyethylene glycol (PEG) grafted to kraft lignin (KL). The results showed that PEG-grafted-lignin increased the fluidity of MMT-contained cement paste when combined with PCE. It improved the rheological properties of MMT-contained cement paste by reducing the yield stress and the rheological behavior index. The adsorption of PEG-grafted-lignin on MMT was more quickly than KL and the equilibrium adsorption amount was 31.43 mg/g at an initial concentration of 100 mg/L. XRD revealed that PEG-grafted-lignin had inserted into the interlayer structure of MMT, while DLS disclosed the spatial effect of PEG-grafted-lignin was much stronger than PCE. This study put forward a new method in the anti-sludge study of PCE.
