Abstract: Historical buildings in Slovenia were mainly built with lime-based mortars. When such buildings are repaired and/or strengthened, materials compatible with existing ones should be used. With that in mind, several lime-based compositions of mortars and grouts with mineral additives were designed and subjected to testing in fresh and hardened state. Among available limes, hydrated lime in powdered state and lime putty were used. Ground granulated blast furnace slag (GGBS), volcanic tuff, and limestone powder were used as mineral additives. Adequate fluidity of grouts was attained with the help of naphtalensulphonate based superplasticizer (SP). First, the influence of different proportions of used materials on the properties of mortars and grouts in fresh and hardened state was analysed. In the next part of the study, the proportion of particular constitutive material was optimized in order to achieve better properties. The obtained results enabled us to evaluate the advantages and deficiencies of both lime types and mineral additives used in the research campaign.
