4. Properties of Fresh SCC

Try these first

1. 1.

   What is the ideal slump flow range for SCC?

   Hint

   Look at the tests for flowability.

2. 2.

   What does T500 time measure in SCC?

   Hint

   Focus on how viscosity is assessed.

3. 3.

   What is the ideal slump flow for SCC?

   • 400-600 mm
   • 650-800 mm
   • 900-1000 mm

   Hint

   Refer to slump flow tests.

4. 4.

   True or False: The V-Funnel test assesses the viscosity of SCC.

   • True
   • False

   Hint

   Think about what aspect of flow it examines.

5. 5.

   Analyze a scenario where SCC's properties would be particularly beneficial for a construction project. Discuss the properties that apply and why they are important.

   Hint

   Consider complex vertical forms that require efficient filling.

6. 6.

   Imagine SCC fails the V-Funnel test, indicating slow flow. What could be the potential causes and suggestions for improvement?

   Hint

   Think about what factors influence flow characteristics in SCC.
