Interpreting chemistry and technology of lime binders and implementing it in the conservation field

Ephorate of Modern Monuments of Central Macedonia, Greek Ministry of Culture Mouson 89, 54634 Thessaloniki, Greece


The objective of the paper is the compilation, review and dissemination of updated scientific knowledge on lime theory and technology in the field of heritage conservation. The strong evidence of the last decade's research on the positive effect of the - not demonstrable by a chemical equation – 'key' missing link of the maturation process is highlighted. It is demonstrated that the exceptional perfor -mance characteristics of durable lime based mortars predominately rely on the capacity for rapid, efficient and extensive carbonation of the air-hardening phase of limes, in particular when matured (nanoparticle wet slaked) lime putties are used; and on the chemical and mechanical stability of the strength components (principally CSHs) of the hydraulic phase of limes, which is higher in their more crystalline forms of historical lime-pozzolan mixtures than in their amorphous forms of modern cements. Hence, physicochemical adhesion and cohesion bonds both at the lime matrix and at the binder/aggregate interfaces are ensured imparting minimization of cracks and durability to lime based mortars and historic masonries. The comprehensive documentation of the former leads to optimal materials and procedures to preserve our cultural heritage.
