Determine Unconfined Compressive Strength of Cohesive Soil
The unconfined compressive strength (qu) is the load per unit area at which the cylindrical specimen of a cohesive soil falls in compression. qu = P/A Where P= axial load at failure, A= corrected area = , where is the ...
Permeability of Soil by Constant Head Permeameter – Objectives & Procedure
Constant Head Permeability Test The constant head permeability test is a laboratory experiment conducted to determine the permeability of soil. The soils that are suitable for this tests are sand and gravels. Soils with silt content cannot be tested with ...
Determination of Shrinkage Limit of Remoulded Soil
The shrinkage limit of soil is the water content of the soil when the water is just sufficient to fill all the pores of the soil and the soil is just saturated. The volume of the soil does not decrease ...
Determination of Plastic Limit of Soil
What is plastic limit of soil? The plastic limit of a soil is the moisture content at which soil begins to behave as a plastic material. At this water content (plastic limit), the soil will crumble when rolled into threads ...
Determine Liquid Limit of Soil Specimen by Casagrande Method
Determine Liquid Limit of Soil Specimen by Casagrande Method The liquid limit of a soil is the water content at which the soil behaves practically like a liquid, but has small shear strength. It flows to close the groove in ...
Soil Particle Size Distribution by Hydrometer Method
Hydrometer method is used to determine the particle size distribution of fine-grained soils passing 75 µ sieve. The hydrometer measures the specific gravity of the soil suspension at the center of its bulb. The specific gravity depends upon the mass of ...
Determine Particle Size Distribution of Soil by Sieving
To Determine Particle Size Distribution of Soil by Sieving The soil is sieved through a set of sieves. The material retained on different sieves is determined. The percentage of material retained on any sieve is given by Where = mass ...
