Description :
Differences in weathering response characteristics of fine- and coarse-grained Stanton Moor sandstone samples were assessed in a laboratory weathering simulation experiment using a variable combination of salt weathering and freeze/thaw cycles. Data indicated that the greater the range in initial permeability values, the greater the potential for salt and moisture ingress and retention and hence eventual disruption of the fabric of the stone. Evidence suggests that relatively minor structural and mineralogical differences between samples of the same stone type can have a significant influence on weathering behaviour.
