Abstract

Abstract

Graphene oxide nanosheets (GONPs) have unique physical properties, making them effective reinforcing materials. The effects of different amounts of GONPs on the mechanical properties, pore size distribution and microstructure characteristics of cement-based composites were studied in this paper. GONPs prepared cement-based composites at 0%, 0.01%, 0.02%, 0.03%, 0.04%, and 0.05% of the cement mass fraction. The compressive strength and indirect tensile strength of the samples were measured at the 28-day age, as well as thermogravimetric analysis (TGA) and X-ray diffraction analysis; nitrogen adsorption technique was used to study the pore size distribution of the fracture surface of the sample and the microstructure was observed by scanning electron microscopy (SEM). The results showed that by incorporating GONPs into cement-based composites, the maximum compressive strength and indirect tensile strength could be increased by 13% and 41%, respectively. The combination of GONPs and ordinary Portland cement (OPC) significantly reduced the pore size of cement mortar, significantly improved its microstructure, and improved the mechanical properties of cement-based composites.
