9.1. Raw Material Testing

Try these first

1. 1.

   What does cement fineness impact?

   Hint

   Think about the cement's ability to react.

2. 2.

   Name one parameter checked for aggregates.

   Hint

   It relates to particle size.

3. 3.

   What does compressive strength assess in cement?

   • Hydration capacity
   • Load-bearing capacity
   • Setting time

   Hint

   Think about how cement behaves under pressure.

4. 4.

   True or False: Water must only be tested for pH in concrete production.

   • True
   • False

   Hint

   Consider all properties of water that affect concrete quality.

5. 5.

   Design a testing plan for aggregates to ensure they meet specifications for a major concrete highway project.

   Hint

   What parameters would ensure long-lasting quality?

6. 6.

   Analyze the potential consequences of using low-quality water in a concrete mix.

   Hint

   Think about how each property might interact with cement.
