Question

13: The saturated soil sample has a specific gravity
of its solids is 2.65 and water content is 10%
determine its void
ratio​

Answer 1

Explanation:

We can't directly calculate the degree of saturation or the air void ratio. First we need to find the void ratio because e is needed to find the answers.

The porosity is given, therefore we can find the void ratio.       

      (or 58%)

Air void ratio,     Av = n (1-Sr) = 0.41 (1-0.58) = 0.1722          (or 17.2%)

Answer 2

Answer:

Soil is a material composed of five ingredients — minerals, soil organic matter, living organisms, gas, and water. Soil minerals are divided into three size classes — clay, silt, and sand (Figure 1); the percentages of particles in these size classes is called soil texture. ... Relative sizes of sand, silt, clay.

I hope this will be help you.
