Study on the Dispersion of Graphene Oxide in Cement Composites

Abstract

Abstract:The effects of DAs with different DA to GO mass ratio on the GO dispersion and agglomeration were observed in simulated concrete pore solution (SCPS) and cement pastes. The ions and pH of cement pastes increased with the amount of cement increasing, which caused the separation of P-HRWR from the GOs. Thus, GOs were absorbed on the surface of the cement particle resulting in GOs sedimentation.
