Background
Concrete
was once regarded as a durable material with no need of maintenance.
However, it is now generally accepted that structural concrete
does not have an indefinite life, i.e., it deteriorates with
time. Although various mechanisms can cause the deterioration
of concrete structures, they are related to the permeation
properties of the cover concrete, i.e. cover concrete can
be considered as the first line of defence against the penetration
of aggressive substances into the concrete and any of the
consequential physico-chemical deterioration processes. Therefore,
various efforts have been made to develop test methods for
measuring the permeability of cover concrete both in the laboratory
and on site. With increasing cases of pre-mature deterioration
of concrete structures reported, methods which can measure
all the permeation properties (such as absorption, gas permeability,
water permeability and ion diffusion) are essential. In the
context of improving the durability of concrete structures
these tests should be capable of measuring these properties
both in the laboratory and in situ.
This workshop
will present a state-of-the-art report on various non-destructive
testing techniques and monitoring methods, including the 'Autoclam
Permeability System', 'Limpet Pull-off Test, 'Permit Ion Diffusion
Test' and 'Fibre Optic Sensor Systems'. The possibility of
using these instruments for improving the durability of concrete
structures in will be highlighted.
Objectives
The objectives of the workshop are:
=>to
highlight mechanisms of deterioration of concrete structures
and establish the relevance of in situ permeation measurements
for assessing the durability.
=>
to review various methods of measuring permeation properties
of concrete and highlight their advantages and disadvantages.
=>to
introduce novel in situ test methods developed in the U.K.
to measure the permeation properties of concrete.
=>to
demonstrate the benefits of measuring permeation properties
of concrete for the assessment of concrete durability for
a range of practical situations.
=>to
introduce novel fibre-optic based monitoring systems to assist
in health monitoring of reinforced concrete structures.
In order
to achieve these objectives, the workshop will be held jointly
between Queen's University Belfast and City University London,
UK.
