3.2. Aggregate Packing

Try these first

1. 1.

   What is aggregate packing in concrete?

   Hint

   Think about how we arrange building blocks.

2. 2.

   Why is reducing voids important?

   Hint

   Consider how tightly packed materials perform.

3. 3.

   What is the main goal of aggregate packing?

   • To enhance color of concrete
   • To minimize voids and reduce paste requirement
   • To increase water content

   Hint

   Focus on how properties improve.

4. 4.

   True or False: Fine fillers always improve the performance of concrete.

   • True
   • False

   Hint

   Remember the sections discussing supplementary materials.

5. 5.

   How would you approach improving the aggregate packing for a project with a history of cracking?

   Hint

   Think about the mix design adjustments needed.

6. 6.

   Discuss the relationship between aggregate size and water usage in concrete mix design.

   Hint

   Consider the impact of particle size on hydration.
