Abstract

This piece of research was conducted to provide guidance and help to the 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 appeared.
