Transport Properties of Concrete: Measurement and Applications

---

The transport properties of concrete measure the ability of fl uids to move
through it. The equations for them were fi rst documented by the end of the
nineteeth century (Fick 1855 ; Darcy, 1856 ) and applied to concrete by the
middle of the twentieth century (Powers et al ., 1954 ). However, they remain
diffi cult to measure, particularly if the common in situ tests are used.
Interest in these properties has increased as many structures built in the
second half of the twentieth century have suffered durability problems,
particularly corrosion of reinforcement. This corrosion was investigated by
Knudson (1907) and was soon discovered to be caused by chloride transport
through the cover layer (Rosa et al ., 1912 ). All of the major deterioration
mechanisms are controlled by the transport properties.

This book is intended to give an improved understanding of the transport
mechanisms that take place during testing. The particular emphasis of the
work is to show how the fundamental transport properties may be obtained.
Two different types of solution to the equations are presented: analytical
solutions and computer models. In general, it is found that analytical
solutions are useful up to a point, but full solutions require a computer
model. In many cases, the analytical solutions are only used to check the
computer models by running them for a special case.

The work will be of interest to researchers who are measuring or modelling
durability of concrete structures and to practitioners who are evaluating
concrete structures or designing containment structures for fl uids or wastes
and require to know the permeability as part of the design. The analysis
methods which are presented may also be used to confi rm the reliability of
any individual test.
