In this report we present a survey of the current
knowledge of the transport properties of concrete. The
basic theory and measurement methods are discussed.
Emphasis is placed on transport properties (or
mechanisms), such as diffusion, permeability, and
capillary flow, that may play an important role in
degradation processes in high performance concrete. It
is concluded that standard test methods used to predict
the service life of concrete via measurement of
transport properties, especially in high performance
concrete, are, in general, inadequate or need to be
