5.1.D.1. Normal Weight Aggregates

Try these first

1. 1.

   Define normal weight aggregates.

   Hint

   Think about the range of density mentioned.

2. 2.

   Name one type of normal weight aggregate.

   Hint

   Consider common materials used in construction.

3. 3.

   What is the density range for normal weight aggregates?

   • 1200-1400 kg/m³
   • 1520-1680 kg/m³
   • 1800-2000 kg/m³

   Hint

   It is important to remember the upper and lower bounds.

4. 4.

   True or False: Angular aggregates provide better workability compared to rounded aggregates.

   • True
   • False

   Hint

   Consider how the shape affects fitting together.

5. 5.

   If you were to design a concrete mix, which normal weight aggregate would you choose for maximum strength under load, and why?

   Hint

   Consider the shape's effect on performance.

6. 6.

   Analyze how a construction project focusing solely on cost might impact the selection of normal weight aggregates.

   Hint

   Think about the trade-off between initial and long-term costs.
