Characterization of Fresh and Durability Properties of Different Lime Mortars for Being Used as Masonry Coatings in the Restoration of Ancient Constructions

Coatings and plasters are an integral part of masonry cladding, having a fundamental protective aesthetic function. They exposed to numerous aggressive actions, which produce their degradation over time. The utilization lime, as binder in lining mortars, plays important role durability conservation. objective this work is analyze the fresh properties lime-based mortars for application restoration old buildings. Four different kinds were studied with similar workability, using binders lime putty, aerial hydraulic lime. aggregates used consisted sand crushed rock powder. As properties, consistency (by flow table) water retentivity determined. With respect durability-related absorption by capillarity immersion, drying kinetics, carbonation depth studied. Bulk density porosity also obtained. Mortars putty showed higher global while presented lower capillarity. Finally, performance all was overall adequate being applied coatings
