GATE CE 2020 Geotech. Engg. Quiz 1 (App update required to attempt this test)

Choose the correct statement(s) on specific gravity (G)

i. Apparent specific gravity does not account for the voids

ii. Absolute specific gravity does not account for the voids.

iii. Absolute specific gravity is less than apparent specific gravity.

Match List I and List II

A sample of soil was prepared by mixing a quantity of dry soil with 10% by mass of water. Find the mass of this wet mixture (in kg) required to produce a cylindrical, compacted specimen of 15 cm diameter and 12.5 cm deep and having 6% air content.
[Take specific gravity of solids = 2.68]

A soil has specific gravity of its solids equal to 2.65. The mass density of water is 1000 kg/m³. Considering zero air voids and 10% moisture content of the soil sample, the dry density (in kg/m³, round off to 1 decimal place) would be _______.

The plastic limit of soil is 25%. where the soil is dried from its state at plastic limit, the volume change is 25% of its value at plastic limit. The corresponding change from liquid state to dry state is 30% of its volume at liquid limit.

Determine the shrinkage ratio:

A pit has a soil of bulk unit weight 16 kN/m³ and water content = 10%. This soil is excavated and compacted to 2 different location such that the dry unit weight is 15 KN/m³. for 1000 m³ of compacted soil, the quantity of soil to be excavated from the pit in m³ is?
