Estimating the Permeability of A Porous Ceramic Tile

Porous ceramics are widely used for water filtering, improving heat transfer, supporting catalysts, vaporizing liquids, etc. Residential tiles used for water sealing are made from ceramic as well. Moisture infusion analysis based on Richard’s equation is necessary to improve tile quality, and this analysis depends heavily on estimating the tile permeability. The current research demonstrates three techniques for calculating ceramic-tile permeability. The first technique is a theoretical model that requires information about the material's effective diameter and porosity that was obtained via scanning electron microscopy (SEM). The second suggested technique is known as mercury intrusion porosimetry (MIP). The pore size, density, pore volume, and porosity of the ceramic tiles, among other characteristics, are evaluated using mercury in this procedure. The experiment's pressure was varied from 0.1 to 60000 psi. These criteria were used to determine the tile's permeability. The last strategy addressed in this research is the falling-head permeameter (FHP) approach. This procedure involves inserting the specimen into a sealed transparent rectangular conduit. Water is then allowed to pass through it. The rate at which the water level in the duct recedes over time is associated with permeability.All the approaches yield permeability values that are in the same order-of-magnitude of 10-16 m2.
