In Roman aqueducts which outcome results, after initial structural cracking, when water freezes inside?

💡 Explanation

Progressive disintegration occurs due to ice wedging, because expanding ice exerts pressure exceeding the tensile strength of the masonry. This causes accelerated cracking, therefore blocks upstream shift rather than simple flow reduction, given cyclical freeze-thaw cycles.
