Abstract

Analysis of two clay-rich sandstone blocks from a temperate maritime, urban environment indicates that, although structural changes such as scaling and flaking affect only the outer 10-20 mm of stone, the zone of alteration extends well beyond this to a depth of up to 60 mm. This zone of alteration coincides with chemical changes. Salt weathering is a threshold phenomenon where decay is manifest only when a stress/strength threshold is crossed. Consequently, in a structurally and mineralogically variable sandstone, differences in porosity and/or clay mineral may result in different blocks being more susceptible to decay than other blocks
