7.8. Quality Control and Workability Monitoring at Site

Try these first

1. 1.

   What is the recommended frequency of slump tests for less than 5 m³ of concrete?

   Hint

   Consider small batches primarily.

2. 2.

   Why is it important to record slump values?

   Hint

   Think about monitoring consistency.

3. 3.

   How often should a slump test be conducted for more than 15 m³ of concrete?

   • 1 test per batch
   • 1 test every 2 batches
   • 1 test every 3-4 batches

   Hint

   Consider larger volumes and their testing needs.

4. 4.

   True or False: Higher workability always leads to stronger concrete.

   • True
   • False

   Hint

   Think about the water-cement ratio relationship.

5. 5.

   Evaluate how increasing ambient temperature could impact the slump test results and the required adjustments to maintain quality.

   Hint

   Consider the interplay between temperature and hydration processes.

6. 6.

   Design a quality control plan that addresses the potential for workability issues in a major construction project facing hot weather conditions.

   Hint

   Think about inclusive strategies in challenging environments.
