Short title	Heat drives moisture into a low-permeability concrete clog, raising pressure and cracking the surface.
Image title	Cross-section of a concrete slab heated from below by flames. Near the heated face a hot dry zone forms; above it a hatched moisture clog band blocks vapour, shown as dashed arrows stopping at the band. Vapour pressure builds below the clog, cracks open at the heated face and pieces spall from the surface on the left.
