Speech title: Micromechanical Modelling on Electrical Conductivity of Graphene Reinforced Porous and Saturated Cement Composites

Abstract: The incorporation of graphene and its derivatives as inclusions for electrically conductive cement composites is currently under extensive investigations due to their potential applications in structural health monitoring. Experiments have shown that the electrical conductivity of the cement composites is highly dependent on the porosity and the fluid contained in the pores. Therefore, it is necessary to quantitatively predict the overall electrical conductivity of the graphene reinforced cement composites while identifying the effects of the pores and the fluid contained. Taking graphene nanoplatelets (GNPs) as inclusions, samples are prepared by wet method, and the electrical conductivity of the samples with different saturations are tested by four-probe method. Constitutive equations for electron tunneling and interface resistance are established while determining the electrical conductivity of GNP reinforced cement composites (GNPRCC), in which the effects of pore and saturation are incorporated. A hybrid micromechanical model (HMM) with a two-step homogenization frame work and a functionally graded electric double layer (FGEDL) simulating saturated pores is developed for the first time. Our model shows excellent agreement with experimental data for different scenarios compared to other models. It is found for the HMM-FGEDL the enhancement of GNPs needs to be considered before incorporating pores for dry samples, whereas pores need to be considered first for saturated ones. Setting the aspect ratio of pores to be 0.01, which is the consistent with the internal-cracks observed in experiments, is preferred while modelling the electrical conductivity of the GNPRCCs.

Prof. Dr. Hosein Lakzian, Payame Noor University, Iran

Research Areas: 

①Harmonic Analysis

②Applied and Computational Mathematics

③Mathematical Analysis

④Fixed Point Theory

Biography: I am currently working at the Department of Mathematics of Payame Noor University in Iran. I am interested in fixed point theory and applications and also working on the theory of weak amenability of Banach algebras. My new approach is finding the relation between these theories using nonexpansive mappings. I also am collaborating in the projects entitled 'fixed point theory in metric spaces via w-distances' and 'Best proximity point for MT-functions' with other professors from other contries such as Professors Stojan Radenovic, Vladimir Rakocevic, Erdal Karapinar and etc.
