The Mechanical Properties and Micro-Structure of Oil Well Cement Enhanced by Graphene Oxide

Abstract:

The improvement of strength and ductility is a challenging task for application of oil well cement. As a 2D nanomaterial with high strength and toughness, graphene oxide (GO) was used as a reinforcing additive in oil well cement. The mechanical properties and micro-structure of oil well cement enhanced by GO were investigated. The compressive strength and flexrual strenghth of cement stone both showed a good enhancement effect when the content of GO was 0.02% -0.05%. The compressive strength and flexrual strength could increase by 15.8% and 33.5%, respectively. The results of SEM and MIP revealed that GO played a template role in promoting the formation of hydration products and further filled in the pores between the hydration products, which refined the micro-structure and improved mechanical properties of the cement consequently.
