ABSTRACT
During the life of a building, it will go through many changes but many
of these will be unseen; they will be settling, flexing and swelling and
shrinking from the very first day that work begins. The act of building is
very much about the assembly of materials in a particular pattern in
order to produce a structure that will be useful. This act relies onmateri-
als being able to stick together, whether through joints and connections
or through the inherent properties of the materials and the jointing
materials.
