Question 8 In order to determine specific gravity we weigh a sample of aggregate in water why? data No new

Solution

1. We weigh the sample of soil or aggregate in water because we take it as standard fluid and

2. we know exact value of density of water than some other fluids and one more reason water has wetting property than any other fluid using pycnometer method.

3.Density determination by pycnometer is a very precise method. It uses a working liquid with well-known density, such as water.

4. Other reason is that water does not chemically combine with aggregates.

5. It\'s makes the method of determining specific gravity cheaper aa it is easily available than some other suitable chemicals.
