4.6.1. Laboratory Tests

Try these first

1. 1.

   What is the purpose of the fineness test in plaster materials?

   Hint

   Think about how size affects plaster usability.

2. 2.

   What does the setting time of plaster indicate?

   Hint

   Consider how this affects job scheduling.

3. 3.

   What does the fineness test measure?

   • Particle size of binders
   • Adhesion strength
   • Water content

   Hint

   Consider what affects the smoothness of plaster.

4. 4.

   True or False: The compressive strength is only tested after plaster has been used in construction.

   • True
   • False

   Hint

   Think about when quality checks occur.

5. 5.

   Explain how improperly mixed plaster can impact the results of compressive strength tests.

   Hint

   Consider how uniformity is critical in testing.

6. 6.

   Analyze the consequences of failing to perform regular fineness tests during production.

   Hint

   Think about the overall impact on construction quality.
