Application of the burning lime for masonry is known from the eldest ages. In history was empirically discovered, the properties of lime putties and mortars made from it can be modified adding various additives. Inorganic additives with latent hydraulic activity (natural pozzolana, thermal modified rocks) or organic additives (proteins, carbohydrates, organic acids as fruit juices etc.) were used. Beneficial influences of some additives were proven by contemporary science. Application of other additives seemed irrational from present point of view. The aim of this work was determined the influence of some historical additives on lime putties and mortar properties.
