Abstract
Porous geomaterials are among the most abundant engineering materials. The pore space in porous materials offers benefits in the exchange of mass and phases. Such properties are related to many important engineering and scientific phenomena. This presentation will introduce the research activities in my group on understanding, modeling and characterizing a few important multiphysics processes in porous geomaterials relevant to infrastructure sustainability and energy applications. The first aspect is on understanding the volumetric change behaviors of geomaterials subjected to freezing, drying or chemical treatment. The second aspect is on modeling the freezing caused pipeline damages. The third aspect is about modeling and characterization for freezing damage of concrete. The fourth topic is on the multiphysics process involved in unconventional energy (i.e. gas hydrate dissociation). The technical basis and engineering relevance will be described.
