- Description
- Blended lime-cement mortars are commonly used in conservation practices even though they
may show lack of adequate strength and durability for certain cement-lime compositions. This paper focuses
on understanding the hardening reactions and their influence on the strength development, microstructure and
porosity for the cement-lime mortars in various compositions. Mortars composed of 30%, 50% and 70% cement replacement with lime hydrate and lime putty by mass were studied. Cement hydration has been found to contribute to the early stage strength development while carbonation is mostly favoured after 3 days and contributes
to the strength development until 180 days. The degree of carbonation is much more pronounced with increasing
lime content and porosity of the mortars and the reaction is still in progress at 90 days. All the blended mortars
revealed lower compressive and flexural strength than that of the reference cement mortar due to their lower
cement content and higher porosity. Long-term compressive strength development has been achieved after 180
days while flexural strength for certain mortar compositions does not increase beyond 28 days. Unlike cement
mortar, the mortars blended with lime hydrate and lime putty exhibit an elastic-plastic deformation before failure
occurs, which is preferred for repair mortars to adapt to differential settlements and to allow more deformation
under critical stresses in the masonry.
