18.1. Batching Accuracy

Try these first

1. 1.

   What is batching?

   Hint

   Think about how you would mix ingredients for a recipe.

2. 2.

   Why is weigh-batching preferred over volume batching?

   Hint

   Consider potential inconsistencies with measuring by volume.

3. 3.

   What is the main advantage of weigh-batching over volume batching?

   • Less complexity
   • More accuracy
   • Lower cost

   Hint

   Think about the precision of measurements.

4. 4.

   True or False: Volume batching is always more accurate than weigh-batching.

   • True
   • False

   Hint

   Consider the reliability of measurements.

5. 5.

   If a concrete batch is consistently under-strength, what steps would you investigate to ensure batching accuracy?

   Hint

   Look at measuring systems and how materials are stored.

6. 6.

   Discuss how the implementation of a control chart could change the consistency of concrete batches over time.

   Hint

   Consider the role of visual tracking of measurements.
