MARINA EL-ALAMEIN
EGYPT
based on new materials was initiated in
2005. A major cause of on-site damage is
the impact of an erosive seaside climate on
faulty stone material of local origin.
Substantial daily and seasonal variations in
humidity and temperature levels result in
granular disintegration, intensified at the
absorption line. The process could have
been escalated by the considerable salinity
of the cement binder used so far, hence
attempts to replace it with slaked lime. In
chemical terms, slaked lime is also the
better material because it corresponds to the
stone used for the building blocks.
The object chosen for the research
program was the lower drum of a column
from room 1 in H21); tests included
reinforcing and protecting the surface of the
stone through a re-profiling with appropri-
ate mineral mortars. The structure was re-
inforced with a solution of dispersive lime,
which was introduced by drop injection.
Upon seasoning in stable conditions, the
surface was covered with lime plaster
containing quartz sand filler (1 part lime to
1.5 parts sand) [Fig. 12}. The material used
was dispersed lime KALKINIEKTION by
Kalk-Kontor-Germany. Actual conservation
