The field density of a soil can be determined by:

The field density of a soil can be determined by: Correct Answer Core cutter method

Explanation:

The dry density of soil in the field can be determined by:

i) Core cutter method

ii) Sand replacement method

Core cutter method:

  • This method is used to find in-situ unit weight in the case of fine-grained cohesive soils without stones.
  • This method cannot be used in the case of hard and gravelly soils.
  • A core cutter is a cylindrical vessel with open at top and bottom with sharp edges usually having 10 cm diameter and 12.5 cm height with a volume of nearly 1000 cc.

Note:

Both the Proctor compaction test and Modified Proctor compaction test are lab tests to determine the dry density of soil.

Consider the following statements and choose the correct answer:
1. Average density of soil is 2.65 gms. per ml.
2. The spaces present between soil particles in a given volume of soil are called pore spaces
3. Porosity of the soil decreases with the increase in the percentage of organic matter in the soil
4. Macro-pore spaces have little water holding capacity and allow free movement of moisture and air in the soil under normal condition
Consider the following statements: 1. When a soil sample is dried beyond its shrinkage limit, the volume of the soil slowly decrease 2. The plastic limit is always lower than the liquid limit for any type of soil 3. At the liquid limit, the soil behaves like a liquid and possesses no shear strength at all 4. When subjected to drying, the volume of the soil remains unchanged once the water content of the soil goes below its shrinkage limit Which of the above statements are correct? 
A teacher is trying to introduce her class VII students to different kinds of soil. She begins by introducing the names of three kinds of soil i.e. sandy soils, clayey soil and loamy soil. She explains the properties of each soil in term of its particulate nature. She then demonstrates one sample of each kind of soil and shows the students the difference in percolation rate of an examples. How would you evaluate this approach from an inquiry oriented perspective?
