A decrease in water content results in a reduction of the volume of a soil in
Explanation: The shrinkage limit is the water content of the soil when the water is just sufficient to fill all the pores of the soil and the soil is just saturated. The volume of the soil does not decrease when the water content is reduced below the shrinkage limit

See lessDetermination of water content of a soil sample suspected to contain gypsum is made by drying the sample for longer period at a temperature not more than
Certain soils contain gypsum which on heating loses its water if crystallization. If itb is suspected that gypsum is present in the soil sample used for moisture content determination it shall be dried at not more than 800 C and possibly for a longer time.

See lessThe ratio of the difference between the void ratio of the soil in its loosest state and its natural void ratio (e) to the difference between the void ratios in the loosest and fully dense state, is generally termed as
So the ratio of the difference between the void ratio of soil in loosest state and its natural void ratio to the difference between the void ratio in loosest state and fully dense state is called Relative density.

See lessIf C is cohesion, F is factor of safety, γ is unit weight of soil and H is the maximum height of embankment, the stability number, is
Different types of direct shear tests under nonisothermal conditions exist and can be classified depending on the following factors: (1) the type of subject being tested (e.g. a soil specimen or a soil–concrete specimen, (2) the type of loading conditions (e.g. CNL or CNS), (3) the type of thermal lRead more

The high compressibility of clay has been explained by a purely mechanical theory. The laminar-shaped particles form honey-comb structures, which, on being destroyed by an increase in pressure, cause a great decrease in volume.

The maximum load carried by a pile, when it continues to sink without further increase of load, is known as
Explanation: The ultimate load carrying capacity, or ultimate bearing resistance or ultimate bearing capacity Q up is defined as the maximum load which can be carried by a pile and at which the pile continues to sink without further increase of load.

See lessThe soil which contains finest grain particles, is
Clay The correct answer is Clay. Clay soil particles are the finest in their size. Clay soils feel very sticky and roll like plasticine when wet. They can hold total water than most other soil types and, although only about half of this is available to plants, crops seldom suffer from drought.
