Soil mechanics
liquid limit was 25.72%.
It is needed to determine the moist unit weight of the soil for field compaction testing. A silty soil sample has a mass of 612 grams. The soil sample was then covered in beeswax and the combined weight was 650 g. The soil covered in wax, was then immersed in the water and the graduated cylinder registered a volume difference of 404 ml. The wax was gently peeled off the soil. Moisture content = 12% Specific Gravity = 2.78 But if the wax has a specific gravity of 0.94, determine the following: Dry unit weight of the soil Void ratio of the soil % of air in relation to the soil solids of the sample
From Laboratory investigations, the Liquid Limit, plastic limit, natural moisture content and flow index of a soil specimen are obtained as 60%, 27%, 32% and 27, respectively. The corresponding toughness index and Liquidity index of the soil specimen, respectively, are
Determine the shrinkage ratio when the soil sample has a liquid limit of 70%, plastic limit of 50% and the specific gravity of the soil solid is 2.70, determine the shrinkage ratio. Select the correct response: 2.54 2.37 1.37 1.55
