Question

If soil is dried beyond its shrinkage limit, it will show

• A. Large Volume change
• B. Moderate volume change
• C. Low volume change
• D. No volume change

Answer 1

The correct option is D No volume change


$Let:W_B=W_{s}representsshrinkagelimit.$

$W_s$ represents shrinkage limit. If the soil is dried beyond shrinkage limit, soil will not show any volume change.

When water content is reduced below $W_s$, the particles are so closely spaced that volume reduction will not take place and the void starts getting occupied by air.

Note : Shrinkage limit is the minimum water content at which soil is saturated.
