9.3.6. Specific Gravity Test (IS: 1202)

Try these first

1. 1.

   What is specific gravity?

   Hint

   Think about how we compare different materials.

2. 2.

   Why is specific gravity important in construction?

   Hint

   Consider what happens if we use the wrong measurements.

3. 3.

   What does the Specific Gravity Test measure?

   • Color
   • Density
   • Viscosity

   Hint

   Think about what property tells us how heavy a material is.

4. 4.

   True or False: Specific gravity is a dimensionless quantity.

   • True
   • False

   Hint

   Remember if it requires units or not during comparison.

5. 5.

   A construction project requires 1000 liters of a bituminous mix. If the specific gravity of bitumen is measured at 1.02, calculate the total mass of bitumen required.

   Hint

   You’ll need to remember how specific gravity relates to volume and mass.

6. 6.

   Assess the implications if the specific gravity of the bitumen used is significantly below the expected range.

   Hint

   Consider how quality affects longevity in construction materials.
