Job concrete characteristics vary with placing, temperature and curing conditions, though being superior to standard test cylinders if generally subject adequate supervision. Floor slabs generally exceed walls and columns in strength tests. Variations occur in structures on directional exposures and vertically in rapidly placed walls and columns. Highway slab concrete characteristics vary with moisture and temperature and with color of curing media. Field-cured test specimens are generally unlike the structure. Tests of cores cut from structures provide accurate data and are economically possible. The report gives results of tests on specimens cured and cut from structures.
