Abstract:
This article describes the four main transport processes: pressure driven flow, diffusion, electro migration, and thermal migration. In addition to these processes that may cause transport, the author also describes three processes that are internal to the concrete that significantly affect the transport processes: adsorption, capillary suction, and osmosis. This article shows how a systematic scientific evaluation of the transport properties of concrete can contribute to the design and construction process and reduce the whole-life cost of structures.
