Freeze thaw and salt crystallisation testing of nanolime treated weathered bath stone

This paper describes the effects of freeze-thaw and salt crystallisation on weathered Bath stones treated with nanolime. Specimens were characterised using drilling resistance measurements to evaluate the variation in surface and subsurface integrity following application of nanolime and subsequent testing. A number of different regimes used to apply the nanolime are reported. The tests did not suggest any negative impacts due to the presence of nanolime on the freeze-thaw tested specimens, however, evidence of sub-surface damage was observed on some specimens subjected to salt crystallisation
