It is known that the natural soil at a construction site has a void ratio of 0.92. At the end of compaction, the in-place void ratio was found to be 0.65. If the moisture content remains unchanged, then determine: 2 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. For a given soil, prove that: 1 + w, 3 sat Ysat = n sat
A saturated sample of inorganic clay has a volume of 21.4 cm3 and weighs 36.7 g. After drying, the volume is 13.7 cm3. The weight of dry soil is 23.2 g. Determine the following: (a) Water content, (b) specific gravity, (c) void ratio, (d) saturated unit weight, (e) dry unit weight, (f) shrinkage limit.
3. A clay soil is found to have a liquid limit of 75%, a plastic limit of 45% and a shrinkage limit of 25%. If a sample of this soil has a total volume of 30 cm' at the liquid limit and a volume of 16.7 cm' at the shrinkage limit, determine the following: a. Mass of soil at the shrinkage limit b. Shrinkage ratio c. Specific gravity of solids
