From: The design of a legacy indicator tool for measuring climate change related impacts on built heritage
Period |
---|
Near future (to 2020) |
Salts present in fresh stone together with pore size and distribution will determine the initial occurrence of salt weathering. Most susceptible are likely to be Portland and brick |
Medium term (to 2050) |
Surface porosity of stones is likely to alter due to weathering; salt loading from the atmosphere will also change the availability of soluble salt. Salt action is likely to increase in this period |
Far future (to 2101) |
The REMO modeling by climate for culture (C4C) provided to the author for the case study sites [5] suggests a slight reduction in NaCl crystallization while projections by Noah’s Ark and research into deep wetting at Queens suggest salt damage will increase. The outcome remains uncertain |
