3.1.3. Based on Shape

Try these first

1. 1.

   What are the four main types of aggregate shapes?

   Hint

   Think about the basic shapes that can be described.

2. 2.

   Which type of aggregate is known for high workability?

   Hint

   Consider the shape that is smooth.

3. 3.

   Which type of aggregate has the highest workability?

   • Rounded Aggregates
   • Angular Aggregates
   • Flaky Aggregates
   • Elongated Aggregates

   Hint

   Think about the aggregate that is naturally smooth.

4. 4.

   True or False: Flaky aggregates are preferred in high-strength concrete applications.

   • True
   • False

   Hint

   Consider how their shape impacts performance.

5. 5.

   Design a concrete mix for a residential sidewalk that prioritizes ease of placement. What type of aggregates would you choose and why?

   Hint

   Focus on the use-case scenario of low load-bearing requirements.

6. 6.

   You are tasked with ensuring a high-strength concrete mix for a bridge. What aggregate shape should you prioritize, and how would you justify this choice?

   Hint

   Consider constructs needing higher durability and resilience.
