Test: Factors Affecting Compaction of Soil - Question 1

Which of the following factors affects compacted density?

Detailed Solution for Test: Factors Affecting Compaction of Soil - Question 1

Water content, type of soil, addition of admixtures, amount and type of compaction are the various factors which affect the compacted density.

Test: Factors Affecting Compaction of Soil - Question 2

The force which is responsible for withholding of soil particles, of lower content is __________

Detailed Solution for Test: Factors Affecting Compaction of Soil - Question 2

When only a relatively small amount of water is present in the soil, it is firmly held by the electrical forces at the surface of soil particles with a high concentration of the electrolyte.

Test: Factors Affecting Compaction of Soil - Question 3

Higher density and lower optimum water content is easily achieved by _________

Detailed Solution for Test: Factors Affecting Compaction of Soil - Question 3

Well graded coarse-grained soil attains a much higher density and lower water optimum water content then fine grained soil which requires more water.

Test: Factors Affecting Compaction of Soil - Question 4

The maximum density is reached in cohesion less soil when the soil is _________

Detailed Solution for Test: Factors Affecting Compaction of Soil - Question 4

The density reaches the maximum value when the cohesion less soil is fully saturated, on further addition of water, the dry density again increases.

Test: Factors Affecting Compaction of Soil - Question 5

The initial decrease of dry density at lower water content is exhibited in ____________ type of soil.

Detailed Solution for Test: Factors Affecting Compaction of Soil - Question 5

The initial decrease of dry density at lower water content is a characteristic feature of black cotton soils, high swelling clays and fat clays. The optimum water content for such soils ranges between 20 to 25%.

Test: Factors Affecting Compaction of Soil - Question 6

The compacted density is increased when the water content of the soil is _________

Detailed Solution for Test: Factors Affecting Compaction of Soil - Question 6

It has been seen from a laboratory experiment that, as the water content is increased the compact density goes on increasing, until a maximum dry density is achieved after which further addition of water decreases the density.

Test: Factors Affecting Compaction of Soil - Question 7

The amount of compaction greatly affects ___________

Detailed Solution for Test: Factors Affecting Compaction of Soil - Question 7

The amount of compaction affects maximum dry density and optimum water content of a given soil. The effect of increasing the compactive energy results in an increase in the maximum dry density and decrease in the optimum water content.

Test: Factors Affecting Compaction of Soil - Question 8

The dry density decreases in cohesion less soil with an increase in water content due to which of the following reasons?

Detailed Solution for Test: Factors Affecting Compaction of Soil - Question 8

In case of cohesion less soil the dry density decreases with an increase in water content under a low compactive effect, this is due to bulking of sands where in the capillary tension resists the tendency of soil particles to take a density state.

Test: Factors Affecting Compaction of Soil - Question 9

The maximum bulking of sand occurs at a water content between ___________

Detailed Solution for Test: Factors Affecting Compaction of Soil - Question 9

The maximum bulking occurs at water content between 4 to 5 %. On further additions of water, the meniscus is destroyed and the soil particles are able to shift to a closer packing.

Test: Factors Affecting Compaction of Soil - Question 10

The attainment of maximum density of soil at full saturation is due to __________

Detailed Solution for Test: Factors Affecting Compaction of Soil - Question 10

The attainment of maximum density at full saturation is due to the reduction of effective pressure between soil particles by hydrostatic pressure.
