Impact of water-cement ratio and cement content on pore area percentage and chloride diffusion – A molecular dynamics study
Abstract: The exposure of a reinforced structure to water-based settings leads to the occurrence of chloride-induced corrosion, resulting in a reduction in both the durability and performance of the structure. The entry of chloride ions into concrete and the pore area percentage is influenced by several elements, including the degree of humidity, the presence of fractures, environmental conditions, water-to-cement ratio (w/c ratio), and cement content. This research focuses on the utilization …

SYMMETRY AND ASYMMETRY MODEL FOR THERMAL CONDUCTIVITY IN POROUS MEDIA
Abstract: This paper focuses on determining thermal conductivity in porous media using symmetry and asymmetry models. Since porous media are not uniform and homogeneous in most of the cases, anisotropy must be taken into account, what derives in the application of an asymmetry model as thermal gradients are not equal in all directions. The paper demonstrates that, under certain conditions, isotropic conditions, therefore, symmetry model can be applied to non-homogeneous or …

Theoretical Analysis of Volume/Weight Fraction of a Dual-Constituent Composite
Abstract: Conventional equations used in analysis of composite materials are modelled based on volume-averaging principle. The volume-averaging equations were re-evaluated to provide an alternative weight-averaging consideration as a result of the difficulty in practical determination of volume fraction of individual constituents of composite material, especially particulate composite. The equivalent weight-averaging equation analysis showed that density plays a significant determining factor in material selection of individual constituent; and composite density evaluated using …

Relative Permeability Study in Part of Geleki Oil field of Upper Assam Basin
Abstract: Relative permeability is a critical parameter for evaluation of reservoir performance. Relative permeability is a direct measure of the ability of the porous medium to allow flow of one fluid when two or more fluids are present. This flow property is the composite effect of pore-geometry, wettability, fluid saturation, saturation history, reservoir temperature, reservoir pressure, overburden pressure, rock-types, porosity and permeability types. The relative permeability curves are very important in …
