The study shows that adding graphene can significantly improve the strength of concrete, but it also increases water absorption and shrinkage. Producing graphene nanoengineered concrete is of great importance for the construction industry in the future.
Graphene has emerged as one of the most promising nanomaterials because of its unique characteristic of being one of the thinnest yet the strongest material. The strength and durability of a novel surfactant functionalized graphene induced concrete composite has been investigated. The water stabilized graphene dispersion at dosages of 0.5, 0.6, 0.7, 0.8, 0.9, and 1 gm/l were used in concrete composites of nine different mixes. An increase of up to 95%, 55% and 27% is achieved in flexural, tensile and compressive strength respectively due to addition at 1 gm/l dosage of graphene. Vice versa, an increase in water absorption and shrinkage is also observed. The study directs towards yield of a graphene nanoengineered concrete which would be of utmost importance in coming years for a sustainable solution in the construction industry.
