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.

Speech Title: Biology in Concrete

Abstract: In the recent past, Bacterial concrete has been emerged as remedial measure of healing cracks in structures like bridges, Reinforced cement concrete Buildings, Reinforced cement concrete Pipes, Canal Lining, Pavement etc. Crack formation is incredibly common occurrence in concrete structure that permits the water and completely different sort of chemical into the concrete through the cracks and reduces their strength and that additionally have an effect on the reinforcement once it reacts with water, carbon dioxide and different chemicals. So, to solve this problem Henk Jonkers introduced bacterial concrete to repair the cracks occurred in the concrete structures.

In this study, experimental investigations have been carried out to arresting the cracks in the concrete using bacillus subtilis bacteria and calcium lactate. The selection of bacteria depends on its survival in alkaline environment. Bacillus subtilis bacteria with calcite lactate is used in different percentages such as 5% ,10% and 15% of cement weight for M20 and M40 grade concrete with river sand mixes and crushed stone sand mixes as replacement of fine aggregate were presented. Experimental investigations were carried out to study the effect of bacteria on compressive strength, split tensile strength and flexural strength of concrete. The abrasion resistance was measured in terms of cantabro loss for all mixes at the ages of 3 days, 7 days, 28 days and 90 days of curing. Investigation results have shown that the cantabro loss decreases as flexural strength increases. Experimental investigations carried out to study the effect of Bacteria on quality of concrete and dynamic modulus of concrete, Ultrasonic Pulse Velocity (UPV) testing conducted at the age of 3 days, 7 days, 28 days, 60 days and 90 days for different mixtures using cube specimens of plain and crushed stone sand Bacterial Concrete.  The presence of calcite precipitates in the form of calcium caronate in bacterial concrete specimens was examined using a Scanning Electron Microscope. The calcite precipitates were confirmed using X-ray Diffraction and Energy Dispersive X-ray Analysis. An empirical relations proposed between flexural strength and compressive strength, split tensile strength and compressive strength, cantabro loss and compressive strength, cantabro loss and flexural strength, UPV and compressive strength, UPV and flexural strength for bacterial concrete with river sand mixes and crushed stone sand mixes.
