Investigation on effect of Graphene Oxide (GO) on hydration process of Portland cement paste was comprehensively conducted using non-contact electrical resistivity measurement. GO additions from 0.01 to 0.08% by weight of cement were incorporated into cement paste with water/cement ratio of 0.40. The electrical resistivity development of cement pastes incorporating GO additions were monitored by non-contacting measurement method. It shows that the electrical resistivity of GO-cement paste increased at early-age compared to pure cement paste. However, because of ions diffusion caused by GO in liquid phases, the electrical resistivity of GO-cement paste declined increased when high GO additions were incorporated. Moreover, the microstructure characterization indicated that GO can refine the microstructure of GO-cement pastes with more connected hydration products.
