Graphene oxide (GO) is a nanomaterial that has recently demonstrated promising reinforcing effects in cementitious composites. However, the uniform and stable dispersion of GO nanosheets within these composites remains a significant challenge. One proposed approach to achieve uniform GO dispersion is to utilize superplasticizers and pozzolans. This study evaluates the influence of different superplasticizers on the physical and mechanical properties of cement mortars containing GO and blast furnace slag (BFS). Mortar mixtures were prepared with varying GO and BFS content and three distinct superplasticizers. The physical and mechanical properties of these mortars were assessed at different ages to investigate their characteristics and the influence of superplasticizer type. The results indicate that the addition of 0.05 wt% GO yielded the most significant improvements in physical and mechanical properties. Furthermore, the incorporation of 0.03 wt% GO in BFS-containing mixtures led to enhanced mortar characteristics. Additionally, using a lignosulfonate-based superplasticizer with and without BFS resulted in superior strength properties. This suggests a more effective dispersion and enhanced stability of GO nanosheets within the cement matrix.
