Compaction test in the laboratory gave maximum dry unit weight of 18.15 kN/m3 at optimum moisture content of 15%. If specific gravity of soil solids is 2.7, the percentage air voids at optimum moisture content is

Comp. Test.

1. In a liquid limit test, the moisture content at 10 blows was 70% and that at 100 blows was 20%. The liquid limit of the soil, is A 35% B 50% C 65% Onone of these.

It is known that the natural soil at a construction site has a void ratio of 0.92. At the end ofcompaction, the in-place void ratio was found to be 0.65. If the moisture content remainsunchanged, then determine:(a) Percent decrease in the total volume of the soil due to compaction.(b) Percent increase in the field unit weight.(c) Percent change in the degree of saturation

A sample of saturated soft clay has a moisture content of w. The specific weight of solids é ys em g-f/cm' (Table 1). What is the void index, porosity and saturated specific weight of the soil (in g-f/cm). Adopt water specific weight of 1 g-f/cm3.

6. The maximum dry unit weight determined in the laboratory for a quart sand is 102 lb/ft3. In the field, the relative compaction is 90%. Specific Gravity of Sand is 2.70. Determine the void ratio at the maximum dry unit weight condition. Determine the void ratio of the sand in the field condition. Determine the hydraulic conductivity of the sand in the field condition if the hydraulic conductivity of the sand at the maximum dry unit weight condition is 0.30 cm/sec. Using Kozeny-Carman equation.
