Soil samples A and B have void ratios of 0.5 and 0.7 respectively. If 1.5 m³ of soil sample A and 1.7 m³ of soil sample B are mixed to form sample C having a volume of 3.2 m³, which one of the following correctly represents the porosity of sample C?

Given for a sample of river sand:

Void ratio at the densest state = 0.35

Void ratio at loosest stage = 1.1

Which one of the following correctly represents the relative density of the sample prepared with a void ratio of 1.0?

An initial cross section area of a clay sample was 15 sq. cm. The failure strain was 25 % in an unconfined compression test. The corrected area of the sample at failure would be:

If the pores of a soil are completely full of air only, the soil is said to be

A soil sample has void ratio 0.82. The specific gravity of solids is 2.65. If the soil is 50% saturated, what is the water content of the soil?

What will be the factor of safety for a soil sample having specific gravity, 2.65 and void ratio, 85 %? Hydraulic gradient for that soil sample is 0.297

Which of the soil possesses zero plasticity index?
