Abstract

The effect of Graphene Oxide (GO) on the thermal properties of high-strength concrete has been less studied. The mechanical properties, compactness, mineral composition and microstructure of the high-strength concrete with GO addition were examined by heat treatments at different temperatures. The results showed that the enhancement of the residual flexural strength with GO addition was greater than that of the residual compressive strength; GO addition had a significant effect on the mechanical properties of concrete treated at less than 500 ℃; Differential Scanning Calorimeter (DSC) test showed that the high-strength concrete with GO addition required more heats for its decomposition after 500 ℃; The internal pores/cracks of the high strength concrete with GO addition were reduced after the heat treatment at a high-temperature because the producing of new crystals can improve the residual properties of the high-strength concrete
