Geotechnical Engineering Please help me answer this question, and please show your solutions write it properly. Problem 3 A soil sample with a grain specific gravity of 2.67 was filled in a 1000mL container in the loosest possible state and the dry unit weight of the sample was found to be 14.75 N. It was then filled at the densest obtainable state and the weight was found to be 17.70 N. The void ratio of the soil in the natural state was 0.63. Determine the relative density in the natural state.
A clay sample has a void ratio 0.50 in dry state and specific gravity of solids is 2 .7 then its shrinkage limit is (in %)
Explain solution
PROBLEM No. 5 Shrinkage Limit Following are the results of a shrinkage limit test: = 26 cm3 19 cm3 Initial volume of soil in saturated state = Final volume of soil in a dry state 46 g Initial mass in a saturated state = Final mass in a dry state = 32 g Determine the shrinkage limit of the soil Determine the shrinkage ratio Determine the specific gravity of the solids d. If the soil at natural state has a moisture content of 25%, estimate the maximum volumetric shrinkage. Estimate the linear shrinkage. а. b. С. е.
The unit weight of the soil in the field was recorded as 126.360 lb/ft3 with natural water content of 16.020 %. In the laboratory, the soil is tested for its maximum and minimum void ratio which were 0.910 and 0.380, respectively, and the specific gravity of soil solids to be 2.780. Determine the following: in situ void ratio , relative density of the soil , percentage decrease in the void ratio if the relative density is increase by 10%
Following are the results of a shrinkage limit test. Determin the shrinkage limit, in percent, of the soil. Round off to two decimal places.
To find shrinkage limit
The indicative properties of soil types A, B, and C were determined as follows: soil cil soil b 35% 60% 20% 28% 25% 43% 27% 40% 100% 110% 2.63 2.7 49% 26% 35% 10% 45% 2.65 soil A Property Liquidity limit Plasticity limit Percentage of clay materials moisture content Degree of Shiism Specific weight Either type 1 is more effective 2 Its edge density is greater 3 Greater overall density 4 Its porosity is greater .5 Classify soil according to the plasticity diagram.
