Résumé
Carbon-based nanomaterials have been identified as a viable additive to cement for making high performance binders with exceptional properties. However, on a few studies have considered the impact of these additives in combination with the environmentally motivated use of supplemental cementitious materials. In this work, the effect of two carbon-based nanomaterials, graphene and graphene oxide, on the hydration kinetics of cement modified with various levels of ground granulated blast furnace slag has been documented. The hydration was characterized with in-situ calorimetry measurements and thermogravimetric analysis over 28 days. The analysis monitors the phase development and degree of hydration during the cement curing period. The results show a strong synergy between choice of nanomaterial chemistry and the use supplemental cementitious material. High confidence correlations between the degree of hydration and compressive strength, with R2 greater than 0.9, across the various combinations of additives, showing the importance of hydration analysis for predicting the cement properties.
