![]() ![]() It is demonstrated that the exceptional performance characteristics of durable lime based mortars predominately rely on the capacity for rapid, efficient and extensive carbona-tion 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. 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. Finally, a brief conclusion summarises the results of this review. ![]() Part two looks at how recent research has influenced this understanding. Part one introduces the present understanding of the subject of lime and proposes a convenient terminology for conservation purposes. It is hoped that this literature survey will aid the future selection of appropriate mortars for historic buildings. Although the study of the scientific papers that exist concerning the technology of historic lime based mortars and the manufacture of new repair mortars suitable for conservation work is an enormous - but essential - task, a synthesis of the existing knowledge was attempted by examining the evolution of research studies the tendencies, gaps and moreover the questions that recent studies have posed for future research. It is the author’s belief that only through scientific documentation of the advantages of lime can it regain its significance in building conservation and compete effectively with its basic rival viz portland cement.
