The building explosion during the years 1945-1960 will inevitably
lead to increased demolition in the next decades since the lifetime
distribution of structures no longer fulfills its functional social
requirements in an acceptable way. In the building period mentioned
there was a great increase in reinforced and prestressed concrete
construction. Consequently there is now more and more concrete to
be demolished. Increasingly severe demands will be made upon
demolition technology, including the demand for human- and
environment-friendly techniques. On the other hand, the possibility
of disposing of debris by dumping is steadily diminishing,
especially close to major cities and generally in countries with a
high population density. At the same time in such countries and in
such urban areas a shortage of aggregates for making concrete will
develop as a result of restrictions on aggregate working because of
its effect on the environment and because of the unavailability of
aggregate deposits due to urban development. From the foregoing it
follows that recycling and re-use of environment- and
human-friendly demolished and fragmented building rubble should be
considered. The translation of this general problem into terms of
materials science is possible by forming clear ideas of adhesion
and cohesion: the whole process of demolition, fragmentation, and
recycling or re-use of concrete is to break the bonding forces
between atoms and molecules and to form new bonds across the
interfaces of various particles of either the same nature or a
different nature.
