Design and production of repair mortars for historic masonry taking into account the characteristics of old mortars

Abstract eng:
This paper focuses on the design and reproduction of crushed brick/lime mortars for the repair of historic masonry. The research presented involves an analytical study of lime mortar samples collected from various archaeological sites and historic buildings in Cyprus. The results of this study are used to determine the physical, mineralogical and petrographical characteristics of these old mortars. Based on the results of the analytical study, a series of compatible repair crushed brick/lime mortars are prepared in the laboratory. The physicomechanical characterisation of these mortars reveals the most important factors which determine their strength, workability and durability. These are: the type and degree of fineness of the ceramic powder, the water/binder (w/b) and binder/aggregate (b/a) ratios and the type of mould. The performance efficiency of the experimental mortars is evaluated through pilot applications on several substrates.
