5.1.C. Based on Shape

Try these first

1. 1.

   What type of aggregates are characterized by smooth surfaces?

   Hint

   Think about where you find smooth stones.

2. 2.

   Which aggregates provide better bonding, rounded or irregular?

   Hint

   Consider how shape affects connection between pieces.

3. 3.

   What type of aggregates has the best interlocking capabilities?

   • Rounded aggregates
   • Irregular aggregates
   • Flaky aggregates

   Hint

   Consider the shapes that fit together well.

4. 4.

   True or False: Flaky aggregates improve concrete strength.

   • True
   • False

   Hint

   Think about how the shape might affect connection.

5. 5.

   Create a comparative analysis of concrete performance using rounded versus angular aggregates in terms of strength and workability. In your conclusion, determine which type is superior for structural applications.

   Hint

   Focus on how the shape impacts the properties of the concrete mix.

6. 6.

   Given a scenario where a concrete structure failed due to poor material selection, evaluate the aggregate types used and propose a better mix for future projects.

   Hint

   Consider interlocking advantages in your new mix proposal.
