3.1.4. Based on Unit Weight

Try these first

1. 1.

   What is the density range for normal weight aggregates?

   Hint

   Refer to the section discussing normal weight aggregates.

2. 2.

   Name one example of a lightweight aggregate.

   Hint

   Think about aggregates that reduce concrete weight.

3. 3.

   Which type of aggregate has a density less than 1120 kg/m³?

   • Normal Weight Aggregates
   • Lightweight Aggregates
   • Heavyweight Aggregates

   Hint

   Think about the aggregates that help with insulation.

4. 4.

   Heavyweight aggregates are primarily used in radiation shielding concrete. True or False?

   • True
   • False

   Hint

   Reflect on the specific applications of heavyweight aggregates.

5. 5.

   Calculate the total weight of a concrete mix that uses 500 kg of normal weight aggregates and 300 kg of lightweight aggregates. Discuss how the weight impacts structural supports.

   Hint

   Analyze how an increase or decrease in weight changes design considerations.

6. 6.

   In a project requiring a radiation shield, determine why it would be inappropriate to use lightweight aggregates even if they are more cost-effective.

   Hint

   Think of the primary role of heavyweight aggregates in this scenario.
