Black cotton soils have :
(A) - High Plasticity (B) Low plasticity
(C) Good shear strength (D) Highly incompressible

The term ‘Drift’ in soil formation relates to :
(4) Deposits made by glaciers
(8) Deposits formed by melting of glaciers
(C) Lateral movement of soil
(D) Fissures formed in lateritic rocks

Degree of saturation of soil refers to : _
(^) Ratio of the volume of voids to the volume ग soil
(B) Ratio of the volume of water to the volume of voids
(©) Ratio of the volume of water to the volume of soil
(D) Ratio of weight of water to the weight of solids

70% ೩ soil with specific gravity 2.6 and dry unit weight of 20 KN/m® (unit weight of
water = 10 KN/m®) the void ratio will be :

@ 0.7 @) 0.52

(0) 0.769 (2) 0.8

If 60% of a soil sample is finer than 0.06 mm and 10% of it is finer than 0.004 mm, its
uniformity coefficient will be :

(ಹ) 0.0667 (8) 5
© 15 (D) 4
- A soil with a consistency index of zero indicates that :
(മ Soil is at the liquid limit (B) Soil attained its plastic limit
(೮) Soil is hard (D) Soil has good shear strength

If the effective grain size of a soil is 0.2 mm and Allen Hazen’s C is 15, its coefficient of
permeability is :

(ക) 0.30 mm/sec (8) 0.60 mm/sec

(C) 0.3 cm/sec (D) 0.6 cm/sec
