For non-hydraulic limes, the fundamental dilemma is, of course, that limes cure by carbonation, and cavities to be grouted are places in walls where little or no air is available. Our work has therefore focused on the use of pozzolanic admixtures, and in particular on dehydroxylated clay. The paper describes the technical challenges associated with the development of a lime-metakaolin grout, created as part of an engineered “port” anchor system for structural stabilization in multiple lifts. Among these challenges are the competing requirements of fluidity, control of water, and the incorporation of aggregates to minimize shrinkage. The first large-scale use of the low-strength grout was in the fall of 2012, in the northeastern United States. Study of the lime-metakaolin formulation is on-going, with the potential to create a range of conservation materials, including crack fillers and repair mortars.
