摘要

Lucknow monuments which date back to 17-18th century are large masonry structures built using thin burnt-clay bricks (lakhauri) and lime-crushed brick aggregate (surkhi) mortars. Studies were carried out to characterize engineering properties of old masonry materials and new mortars being used for the renovation work. Mechanical properties of reclaimed lakhauri bricks were found comparable to good-quality contemporary bricks of the neighbouring region. Moreover, XRD and SEM-EDS analyses indicated that mineralogical composition is not too different, except few minerals. The lime surkhi mortar used in old masonry work was found to be lime rich with binder to aggregate ratio of about 1 : 2 to 3 by volume and is similar to those used in Byzantine structures of Western and Central Asia. The renovation mortar had poor hydraulic property compared to old mortars indicated by TG-DTA analyses.
