7.8. Quality Control in High Performance Concrete

Try these first

1. 1.

   What is the purpose of conducting material quality checks?

   Hint

   Think about what happens if the materials are substandard.

2. 2.

   Name two tests performed on fresh concrete.

   Hint

   Consider what we measure to see if it will work well when poured.

3. 3.

   What is one of the key reasons for conducting quality control tests on HPC?

   • To increase costs
   • To ensure consistency in performance
   • To reduce workforce needs

   Hint

   Consider what quality control helps in delivering to the construction industry.

4. 4.

   True or False: Fresh concrete testing includes checking the air content.

   • True
   • False

   Recall the various tests performed on fresh versus hardened concrete.

5. 5.

   Develop a quality control checklist for materials used in HPC production. Justify the inclusion of each item on your list.

   Hint

   Think about specific tests that align with industry standards for each material.

6. 6.

   Analyze a scenario where improper batching leads to a project failure. Describe the factors involved and potential solutions.

   Hint

   Consider what happens when ingredients don’t fully intermingle.
