alleryStart learning →Per Table 5.1, the slump range corresponding to a 'HIGH' degree of workability is approximately:
A0 to 25 mm slump
B25 to 50 mm slump
C50 to 100 mm slump
D100 to 175 mm slump
Answer & Solution
Correct answer: D. 100 to 175 mm slump
1. Table 5.1 places the 100-175 mm slump range in the 'High' workability band, with a corresponding compacting factor near 0.95-0.96.
2. Such mixes suit sections with congested reinforcement that cannot be vibrated.
