Experimental Investigation on Strength and Durability of Graphene Nanoengineered Concrete

Effects of using aqueous graphene on behavior and mechanical performance of cement-based composites

“…Additionally, nucleation in the pore space removes calcium and hydroxide ions from the solution, thereby creating a local concentration gradient away from the clinker particles, which further accelerates PC clinker dissolution [17,18]. In recent years, graphene has been deployed as nanoparticles to enhance the performance of cement-based materials [19][20][21][22][23] due to its outstanding properties to form graphene-reinforced cement composites for smart infrastructures. Graphene, a single-layer of sp2 bonded sheet of carbon atoms arranged into a 2D honeycomb lattice pattern (with an interlayer thickness of ~0.335 nm), has intrinsic high mechanical properties (i.e., the strength of ~100 GPa and the Young's modulus of 1 TPa [24]) therefore has potential to greatly improve the mechanical properties of cementitious materials.…”

A comprehensive review of MXenes as catalyst supports for the oxygen reduction reaction in fuel cells

“…Graphene is the thinnest 2-dimensional (2D) carbon material with an atomic thickness of 0.335 nm 6 but is considered the strongest material to be discovered. 7 However, in the real operational condition of PEMFCs, these carbon-based material supports are rapidly corroded, causing degradation of the electrocatalyst. In addition, 2D graphene tends to aggregates which leads to a decrease in the specific surface area, resulting in poor ion transport capabilities.…”

Nano-modification in digital manufacturing of cementitious composites

“…It is also possible to design GOs with hydrophobic properties, then it is applied as a coating material, decreasing water absorption, capillary absorption and chloride ingress considerably (Habibnejad Korayem et al, 2020). However, some researchers (Dalal & Dalal, 2021) have reported problems with excessive shrinkage, which requires further study.…”
