5.2.2.4. Ten Percent Fines Value

Try these first

1. 1.

   What does TPFV stand for?

   Hint

   Think about the percentage related to the fines.

2. 2.

   What does a lower TPFV value indicate?

   Hint

   Consider what it means for load resistance.

3. 3.

   What does the Ten Percent Fines Value (TPFV) measure?

   • The load for producing fines equal to 10% of the aggregate weight
   • The overall strength of concrete
   • The density of aggregates

   Hint

   Think about what percent value relates to fines.

4. 4.

   True or False: A high TPFV indicates high-quality aggregates.

   • True
   • False

   Hint

   Consider what happens to aggregates under load.

5. 5.

   If you have two aggregate samples, one with a TPFV of 15% and another with 30%, which would you choose for a high-durability concrete project? Justify your answer based on TPFV significance.

   Hint

   Remember, lower TPFV values are desirable.

6. 6.

   In a recent project, the concrete failed due to poor aggregate quality. Analyze how TPFV testing could have prevented this issue.

   Hint

   Consider the role of TPFV in quality assurance.
