Question

________ structure is highly compressible and less permeable.

(a) Flocculent

(b) Dispersed

(c) Honeycomb

(d) Singe grained

I had been asked this question in exam.

I would like to ask this question from Flocculent and Dispersed Structures topic in section Soil Structure and Clay Minerology of Geotechnical Engineering I

Answer 1

The correct answer is (b) Dispersed

The explanation is: The dispersed structure has face-to-face contact in an approximately parallel manner having a lesser void ratio. Thus they have highly compressibility and less permeability. Whereas, the flocculent structures have low compressibility and high permeability.
