Challenge Problems

Push your limits with challenges.

Question 1

A concrete contractor is faced with a very thin slab and dense reinforcement, making it impossible to insert an internal vibrator. What approach should they take to ensure proper consolidation?

💡 Hint: Consider the restrictions imposed by slab thickness and reinforcement density.

Question 2

A batch of concrete has a slump of 85 mm. Discuss the implications of using surface vibrators and compare that with the use of form vibrators.

💡 Hint: Analyze how workability affects the performance of different types of vibrators.
