TO DETERMINE THE PERMEABILITY OF A SOIL SPECIMEN BY THE VARIABLE HEAD PERMEAMETER Theory: The variable head permeameter is used to measure the permeability of relatively less pervious soils. The coefficient of permeability is given by ...

## PERMEABILITY OF SOIL BY CONSTANT HEAD PERMEAMETER

TO DETERMINE PERMEABILITY OF SOIL BY CONSTANT HEAD PERMEAMETER. Theory: The coefficient of permeability is equal to the rate of flow of water through a unit cross section area under a unit hydraulic gradient. In the constant head permeameter, the head causing ...

## DETERMINATION OF SHRINKAGE LIMIT OF REMOULDED SOIL

TO DETERMINE THE SHRINKAGE LIMIT OF A SPECIMEN OF THE REMOULDED SOIL Theory: The shrinkage limit 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 ...

## DETERMINATION OF PLASTIC LIMIT OF SOIL

TO DETERMINE THE PLASTIC LIMIT OF A SOIL SPECIMEN Theory: The plastic limit of a soil is the water content of the soil below which it ceases to be plastic. It begins to crumble when rolled into threads of 3mm diameter. Equipment: 1. Porcelain ...

## THE LIQUID LIMIT OF SOIL TEST

TO DETERMINE THE LIQUID LIMIT OF A SOIL SPECIMEN Theory: 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 just ...

## PARTICLE SIZE DISTRIBUTION OF SOIL BY HYDROMETER METHOD

TO DETERMINE THE PARTICLE SIZE DISTRIBUTION OF SOIL BY HYDROMETER METHOD Theory: Hydrometer method is used to determine the particle size distribution of fine-grained soils passing 75 sieve. The hydrometer measures ...

## PARTICLE SIZE DISTRIBUTION OF SOIL BY SEIVING

TO DETERMINE THE PARTICLE SIZE DISTRIBUTION OF A SOIL BY SEIVING Theory: 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 ...

## DRY DENSITY OF SOIL BY WATER DISPLACEMENT METHOD

TO DETERMINE THE DRY DENSITY OF A SOIL SAMPLE BY WATER DISPLACEMENT METHOD Theory: A soil specimen of regular shape is coated with paraffin wax to make it impervious to water. The total volume (V1) of the waxed specimen is found by ...

## IN-SITU DRY DENSITY BY SAND REPLACEMENT METHOD

TO DETERMINE IN-SITU DRY DENSITY BY SAND REPLACEMENT METHOD Theory: A hole of specified dimensions is excavated in the ground. The mass of the excavated soil is determined. The volume of the hole is determined by filling it with clean, uniform sand whose ...

## SPECIFIC GRAVITY OF SOIL BY PYCNOMETER METHOD

How to Determine Specific Gravity of Soil by Pycnometer Method? The Pycnometer is used for determination of the specific gravity of soil particles of both fine grained and coarse grained soils. The specific gravity of soil is determined using the relation: ...
