β-Cyclodextrin Substituted Polyoxyethylene in the Synthesize of Polycarboxylate Superplasticizers

Abstract:

In this study, the starch-based material β-cyclodextrin was used as the original material to substitute petrochemical product-polyoxyethylene (HPEG) to synthesize concrete admixture polycarboxylate superplasticizer (PCE). During the synthesis, β-cyclodextrin was first grafted on the PEO chain to prepare β-CD-HPEG by click reaction. Then β-CD-HPEG was used to substitute the macromonomer HPEG to synthesize β-CD-PCE. When the substitution amount HPEG was 3%, the synthesized β-CD-PCE showed better dispersion ability.
