This project investigates the potential of in situ precipitation of calcite (CIPS) for use in conserving stone masonry. CIPS was developed for improving insitu the geotechnical properties of soil and involves permeation of a solution from which a large volume of the mineral calcite (calcium carbonate) precipitates in a controlled manner. It replicates natural calcite cementation processes in days instead of geological time periods and for rocks originally containing calcium carbonate has the potential for providing a far more attractive method of conservation than existing methods. The project would involve developing an improved understanding of the solution chemistry of CIPS, optimising it for application to stone masonry, applying CIPS to a range of rock types and mortars of varying degrees of deterioration in the lab and in situ, characterising the effect of CIPS on microstructure, mechanical properties and transport properties, assessing the durability of the CIPS treatment and developing recommendations concerning situations where CIPS is likely to be effective and where it is not.
