Fresh and hardened properties of GGBS-contained cementitious composites using graphene and graphene oxide

The addition of nanomaterials affects the workability cementitious composites by reducing free water available within mixtures. In order to address this issue, present study intends ground granulated blast furnace slag (GGBS) in materials containing graphene (G) and oxide (GO). An experimental program is considered measure fresh properties, compressive strength, service life composites. Dosages 0.03% 0.06% (by weight cement) G GO are tested cement pastes mortars. GGBS three different dosages 15%, 30%, 45% investigated. A constant water/cement ratio 0.35 used all Results show that improves yield stress plastic viscosity G- GO-modified Moreover, 30% compensate reduced fluidity 0.03 wt% composites, respectively. thixotropy composite paste decreases with GGBS. comparable slightly improved strengths obtained for mixtures results from nomogram a promising trend G, GO,
