Abstract Two different sizes of graphene (Peeling graphene, PG) slurry were dispersed, and then the graphene cement mortars were prepared. Carbonization test of graphene cement mortar at different ages was conducted by rapid carbonization methods. Composition and hydration pro-ducts of graphene cement-based materials were observed by X-ray diffraction (XRD), scanning electron microscope (SEM) and X-ray energy dispersive spectroscopy (EDS) tests. The microscopic morphology of graphene cement-based materials and hydration products were observed. The test results showed that at the age of 56 d, the carbonation depths of the large-size graphene (PG1) and small-size graphene (PG2) cement mortar samples were 3.7 mm and 5.5 mm, respectively, which were 58.4% and 38.2% lower than those of the blank sample. Using the lm function of R language, the nonlinear regression prediction models on the carbide depth of the three cement mortar test blocks at different ages were established, the relationship between carbonation time and carbonation depth was investigated. The simulation results have a high agreement with the experimental measured values.
