This book describes procedures and methodologies used predominantly
to obtain a diagnosis of damaged concrete possibly caused by
Alkali-Aggregate Reaction (AAR). It has two primary objectives,
namely firstly to identify the presence of AAR reaction, and
whether or not the reaction is the primary or contributory cause of
damage in the concrete; and secondly, to establish its intensity
(severity) in various members of a structure. It includes aspects
such as field inspection of the structure, sampling, petrographic
examination of core samples, and supplementary tests and analyses
on cores, such as mechanical tests and chemical analysis.
Evaluation of test data for prognosis, consequences and appraisal
will be more fully set out in AAR-6.2.
Self-healing materials are man-made materials which have the
built-in capability to repair damage. Failure in materials is often
caused by the occurrence of small microcracks throughout the
material. In self-healing materials phenomena are triggered to
counteract these microcracks. These processes are ideally triggered
by the occurrence of damage itself. Thus far, the self-healing
capacity of cement-based materials has been considered as something
"extra". This could be called passive self-healing, since it was
not a designed feature of the material, but an inherent property of
it. Centuries-old buildings have been said to have survived these
centuries because of the inherent self-healing capacity of the
binders used for cementing building blocks together. In this
State-of-the-Art Report a closer look is taken at self-healing
phenomena in cement-based materials. It is shown what options are
available to design for this effect rather than have it occur as a
"coincidental extra".
