The Liquid Limit and Plastic Limit of sample are 40% and 30% respectively. If 20% of the soil is finer than 0.002 mm then the activity ratio of the soil sample would be:

A carefully-weighed 52.9 gram soil sample was dispersed for particle-size analysis using the Bouyoucos hydrometer method. The laboratory was held at a constant temperature of 20 C (68 F). The hydrometer reading after 40 seconds was 20.1 and the hydrometer reading after 8 hours was 5.1. What percentage of particles in the soil sample were clay-sized? Your Answer: Answer units

The moisture content of the natural soil as obtained from the oven drying method is 8 % and its unit weight in the natural state is 17.6 kN/m³. The laboratory test on the soil sample revealed that the void ratio in its loosest and densest state are respectively 0.76 and 0.45. If the specific gravity is assumed to be 2.65, then the relative density (in percentage, correct up to two decimal places) of the soil sample is (Take g = 9.81 m/s²) Answer ㅋ

Can u solve ?(readable)  A soil specimen is 38 mm in diameter and 76 mm long, and in its natural conditionweighs 168.0 g. When dried completely in an oven, the specimen weighs 130.5 g. The value ofGs is 2.73. What is the degree of saturation of the specimen?
