Try these first

1. 1.

   Define Angular Aggregates.

   Hint

   Think about their shape and its impact on concrete.

2. 2.

   What property do angular aggregates enhance in concrete?

   Hint

   Consider how particles fit together.

3. 3.

   What type of aggregate is characterized by sharp edges?

   • Rounded
   • Angular
   • Flaky

   Hint

   Consider the shape and its impact on concrete.

4. 4.

   True or False: Angular aggregates reduce the strength of concrete.

   • True
   • False

   Hint

   Recall how they fit together.

5. 5.

   Design a concrete mix for a highway that uses angular aggregates. Discuss how you would manage workability while ensuring high strength.

   Hint

   Think about the balance between workability and strength.

6. 6.

   Evaluate the impact of using angular aggregates on a bridge's long-term durability compared to rounded aggregates.

   Hint

   Consider long-term structural needs and the types of loads on a bridge.
