Permeability of stressed concrete

Abstract

Abdy Kermani of the Structural Research Group at the Department of Civil Engineering, Napier Polytechnic of Edinburgh, found that permeability increases with increase in applied stress level depending on the type of the mix and the magnitude of the applied pressure. He also found that additives, which affect the composition, strength and propagation of micro cracks in concrete, can also have a significant influence on permeability.
