Graphene-Enhanced SCMs: Impact on Cement Paste Properties

Abstract

This study investigates the influence of supplementary cementitious materials (SCMs), specifically slag and fly ash, in conjunction with graphene nanomaterial on the properties of cement paste. Graphene, a two-dimensional carbon allotrope with extraordinary properties, has emerged as a promising nanomaterial to enhance the performance of various materials, including cement-based composites. This study delves into the synergistic effects of graphene and supplementary cementitious materials (SCMs), specifically slag and fly ash, on the properties of cement paste. The integration of graphene into the cement matrix was found to significantly improve the stiffness and durability properties of the cement paste. Not only that but the mechanical properties, such as compressive strength, flexural strength, and tensile strength also found to be enhanced with the inclusion of graphene in the cement matrix. The results demonstrated that the incorporation of SCMs and graphene significantly improved the mechanical properties, reduced porosity, and enhanced the durability of cement paste. The synergistic effect of SCMs and graphene was found to be particularly beneficial in improving the overall performance of cement paste. The unique properties of graphene, including its high surface area, excellent electrical conductivity, and mechanical strength, contribute to its effectiveness in improving the overall performance of cement-based materials. This study highlights the potential of graphene as a sustainable and high-performance additive for future generations of cement matrix study.
