For structural concrete on Florida highway projects, target slump values are specified in Table 346-3 with tolerances of ±1.5 inches for conventional concrete (e.g., Class II, III, IV, V, VI, VII). For Class IV (Drilled Shaft), target slump is 3 inches (±1.5 inches) unless noted otherwise. SCC requires a minimum slump flow of 22.5 inches (±2.5 inches) with Engineer approval [2][5].
