Deterioration Problems of Ankara Castle Andesites

Ankara castle is the symbol of the capital city. The
history of Ankara Castle goes back to the Hittite
periods. The surface of Ankara Castle andesite
blocks were heavily weathered over the years.
This book aimed to identify deterioration problems,
repair and conservation
needs of andesites on the walls of the Ankara
Castle. Decay forms of walls were documented by
visual examination. Samples taken from the surface
of the weathered andesites were examined for their
basic physical, mechanical compositional and
minerological properties. Soluble salt content of
the andesite samples was determined by spot tests
of anions and electrical conductivity measurements.
Findings were evaluated in terms of the long-term
weathering behaviour of andesites under the effect
of the prevailing climate, air pollution problems of
Ankara, dampness problems of the structure,
previous repairs with incompatible cement mortars.
This book should be help shed some light on
conservation and restoration of the historical
monuments, and should be especially useful to
professionals and students in conservation and
restoration.
