Unusual case of freezing of fresh concrete
Detailed examination of floor slabs in Platteville Elementary School Bldg, Platteville, Colo, both at site and by microscopical examination of drilled cores; results showed that upper 1/2 to 1 1/4 in. of concrete had been frozen before hardening, causing intense fracturing of near surface portion and producing bumps over originally frozen lumps of sand and shale incorporated in concrete.
