Abstract

Lime mortars are preferred for repair of historic masonry because their greater flexibility enables them to accommodate expansion and contraction in service without damaging the stone but there is little information on properties of mortars made with commercially available limes. Binder hydration rate and workability of mortars using Natural Hydraulic Limes of grades NHL2, NHL3.5 and NHL5 from four manufacturers is reported. Significant differences in the hydration rates between different limes offer the possibility of a better classification system. However, the variation in the workability between different products could pose challenges to users and specifiers of mortars for masonry repair.
