Abstract

Graphene oxide nanomaterials can significantly alter and enhance the microstructure of cementitious materials, thus improving their mechanical properties and durability and bringing about a variety of functionalities of cementitious materials. In this paper, the role of graphene oxide (GO) on cement hydration process and its important hydration products, calcium hydroxide (CH) and hydrated calcium silicate gel (C-S H), was investigated under an adaptive network model. Various GOs were characterized analytically using high atomic force microscopy and transmission electron microscopy techniques, and both the hydration process and the concentration of their hydration products were measured in freshly mixed aqueous mortars with various GO admixtures using heat of hydration, X-ray diffraction studies and thermal reanalysis tests.
