7.2.1. Slump Test

Try these first

1. 1.

   What is the primary purpose of the Slump Test?

   Hint

   Think about what workability means in construction.

2. 2.

   What does a true slump indicate?

   Hint

   Consider what good workability looks like.

3. 3.

   What does the Slump Test measure?

   • A) Dryness of concrete
   • B) Color of concrete
   • C) Workability of fresh concrete
   • D) Weight of concrete

   Hint

   Remember what the test aims to evaluate.

4. 4.

   True or False: A collapse slump indicates good workability.

   • True
   • False

   Hint

   Think about what a collapse means for the concrete.

5. 5.

   In a construction site, the concrete shows a collapse slump consistently. What problems might arise from using this concrete, and what steps could you take?

   Hint

   Consider the effects of excess water and how it could be managed.

6. 6.

   A batch of concrete fails the Slump Test, showing a shear slump. What adjustments could you recommend to improve cohesion?

   Hint

   Think about what changes can increase the stability of the mix.
