Morphed graphene as reinforcement for oil-well class G cement composites

Morphed graphene (MG) has only recently been put forward as the perfect reinforcement composite material for structure composites due to its unique mechanical properties. This article addresses the possibility of applying MG as a toughener phase in composites of cement for oil-well. MG was synthesized from petroleum coke through control milling and incorporated into cement with varying concentrations (0.1–1 %). The mechanical behavior of MG-reinforced cement demonstrated significant improvements, including enhanced fracture energy, flexural strength, and compression strength. Electron microscopy morphological analysis confirmed that MG effectively reduced porosity and improved particle cohesion. • Advanced morphed graphene–cement composite with enhanced performance. • Morphed graphene ensures better dispersion and bonding. • Boosted mechanical properties: strength and toughness.
