Question

Clay present in the marine area has ________

(a) Flocculent structure

(b) Dispersed structure

(c) Honeycomb structure

(d) Singe grained structure

I have been asked this question in an interview.

The origin of the question is Flocculent and Dispersed Structures in section Soil Structure and Clay Minerology of Geotechnical Engineering I

Answer 1

The correct answer is (a) Flocculent structure

To explain: The salt present in the marine water acts as an electrolyte and thus reduces the repulsive forces between the particles which leads to the formation of the flocculated structure. The have high shear strength.
