5.1.D. Based on Density

Try these first

1. 1.

   What are the three types of aggregates based on density?

   Hint

   Think about their weight classifications.

2. 2.

   Which aggregate type is known for reducing weight in structures?

   Hint

   Consider the implications of weight reduction in construction.

3. 3.

   What is the density range for normal weight aggregates?

   • 1520–1680 kg/m³
   • 1120–1520 kg/m³
   • >2000 kg/m³

   Hint

   Recall the normal weight aggregates discussed in class.

4. 4.

   True or False: Lightweight aggregates have a density greater than 1120 kg/m³.

   • True
   • False

   Hint

   Consider the definitions you learned.

5. 5.

   In what scenarios would using lightweight aggregates outweigh the potential increased water absorption rates? Discuss with examples.

   Hint

   Consider applications focusing on sustainability.

6. 6.

   Evaluate the importance of heavyweight aggregates in environmental contexts, such as in projects near radiation sources.

   Hint

   Think of the implications for health and safety in construction.
