    ENHANCING CONCRETE MECHANICAL PROPERTY USING LIQUID PHASE SHEAR EXFOLIATED GRAPHENE NANO PLATE
    (Hawassa University, 2019-10-19) KIBROM GETACHEW BELAY
    Present investigation deals with the methods adopted to produce and introduce Liquid phase shear exfoliated multi-layered Graphene. Recently, the development of an ideal Nano-material called graphene in modern science create an opportunity to develop better performing Nano-engineered materials. Thus, the compression and splitting tensile test result for 50% and 100% replacement of mixing water by produced Graphene solution, related modulus of elasticity is calculated based on compression result obtained. Such way that 28 days’ compression capacity show 33.4% and 16.5% improvement for 50% and 100% replacement of mixing water with Graphene solution. Moreover, the 28 days splitting tensile strength test result show 43% and 10% improvement for 50% and 100% replacement of mixing water with Graphene solution. The chemical crystalline matrix crushed pieces of test samples of Graphene solution made concrete were confirmed by using scanning electron microscope (SEM). Here we report that a significant enhancement of mechanical properties of the Graphene solution produced concrete than the conventional concrete.
