1. Data from a sieve analysis conducted on a given sample of soil showed that 67% of the particles passed through a 75 micron IS sieve. The liquid limit and plastic limit of the finer fraction was found to be 45 and 33 percent respectively. The group symbol of the given soil as per IS: 1498-1970 is

• SC

• MI

• CH

• MH

20) For a soil in natural state, void ratio is 1, water content is 30% and G-2.50, the degree of saturation

• 0%

• 150%

• 75%

• 30%

The wt. of a container is 40gm and the weight of the container and wet soil sample is 100g on oven drying for 24 hrs. the wt. of container with dry soil is found to be 80g. the water content of the soil is….

• 40%

• 50%

• 80%

• 33.33%

18) A soil has a bulk density of 1.80g/cc at a water content of 5%. If the void ratio remains constant, then it bulk density for a water content of 10% will be

• 1.98g/cc

• 1.80g/cc

• 1.70g/cc

• 1.88g/cc
