Research Progress of the Preparation and Properties Graphene Cement Composite

Abstract

Graphehe has extremely great mechanical, electrical and thermal properties that make them ideal reinforcing materials in cement by mixing them homogenously. In this paper, firstly, the dispersion methods of graphene, including physical stirring, surfactant treating and ultrasonication, are presented to obtain stable dispersed surfactant aqueous solution. Then, the mechanical properties of graphene cement composite are studied, such as Young's modulus, shear modulus, compressive strength, flexural strength and toughness. Moreover, the piezoresistivity of graphene cement composite is researched in comparison with plain cement. At last, the durabilities, especially the resistance to chloride ion permeability, freezing-thawing and carbonization, are summarized and compared.
