Effect of Graphene as Additive on the Mechanical Properties of Concrete

Abstract

Graphene is a smart and relatively new material that has promising applications in many engineering fields. Recently it was found that graphene can be produced from burning waste materials which will have an impact on cost and the wide applications in many engineering fields including construction. The addition of tiny amounts of graphene in concrete mixes can enhance the mechanical and durability properties. This research investigated the effect of graphene as additive on the mechanical properties of concrete. The addition percentage (by weight of cement) was 0.02%, 0.035%, and 0.05%. Cubic and cylindrical specimens were prepared to assess the compressive strength, flexural strength, and elasticity modulus of concrete. Results showed that adding graphene to concrete led to an increase in both compressive and flexural strength as well as the modulus of elasticity. This will help in reducing concrete dimensions in different structural members like columns and beams and will contribute towards sustainable devel-opment.
