conservation architects for the preparation of appropriate lime mortar for the conservation of stone
masonry. A comprehensive research and detailed examination of conservation works on significant
historic monuments in Lahore was carried out in the Department of Archaeology and Museums,
Pakistan. The results provided the analytical description of lime, types of lime and preparation of
Kankar-lime followed by description and analysis of various compositions of lime mortars suggested
by International and National experts of conservation. The mortars for conservation and repair work
should include the same range and a type of aggregate particles was used in the original mortar. More
particularly the original binder and pouzzolanic additives must be used. This must be ensured that new
mortar should necessarily perform and appear in the same manner as the older performed and
