Abstract

Abstract:

In this study，polycarboxylate superplasticizer（PCE） was used to graft onto graphene oxide（GO），thereby synthesizing a novel GO-based superplasticizer（PCE@GO）.The GO modification experiment was simple and feasible.It not only could overcome the agglomeration issue of GO in cement mortar but also enhanced the mechanical properties of the cement mortar by using grafted PCE@GO as a reinforcing material.The experimental results showed that PCE@GO could be uniformly dispersed in the cement solution，with obviously improved stability，due to the steric hindrance and electrostatic repulsion provided by the PC on the surface of GO，which prevented the agglomeration of GO.Furthermore，PCE@GO also significantly enhanced the mechanical properties of the cement paste：when 0.1%（mass fraction） content of PCE@GO was added，the flexural strength and compressive strength of the cement composite material at 28 d reached the maximum values of 8.0 MPa and 65.4 MPa，respectively，which were 6.7% and 23.2% higher than the GO samples with an addition of 0.1% PCE@GO.The addition of PCE@GO also improved the flowability of the cement mortar and reduced the crystal size of the hydration products，thereby enhancing the performance of the cured composite material.This study provided theory and experimental basis for designing and preparing high performance cement mortar materials，and had certain guiding significance for the application of GO-based materials in cement mortar.
