▎ 摘　　要

NOVELTY - Polycarboxylate water reducing agent graphene additive comprises graphene liquid and water reducing agent mother liquid. USE - Polycarboxylate water reducing agent graphene additive useful in building industry. ADVANTAGE - The graphene additive can effectively act on the concrete and can keep the stability in the system for a long time. The additive production environment pollution is small. The graphene oxide directly adding the use effect difference directly in the water-reducing agent production process is avoided. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of graphene liquid.
