Introduction
S.N: 100303438
The quality and characteristic soil samples are needed for the laboratory tests, which will lead
the test to be achieved at highest level of successful results. The sample will need to be
collected from every parts of the site to ensure the site fully tested, especially for large sites
as they contain different type of soil. This will be best option to collect the data about the
conditions of the ground all around the site. The author must ensure that the experiment is
carried to with the British standards and specifications.
The aim of the test is to define the type soil, its conditions and the properties, then it can be
improved to meet the criteria of the British Standard and specifications to with stand for the
propose structure that is going to be built on site.
The purpose of geotechnical is providing with understanding the engineering properties of
soil. As a civil engineer the main duty is to understand the engineering properties such as
shear strength and bearing capacity, because all of their work start off with foundations to
deal with soil.
To enable us to classify the types of soil. We need to carry out the experiments that are
provided by geotechnical:
Sieve analysis test
Liquid limit test and Plastic limit test
Common proctor
Test one
Sieve analysis
A mechanical shaker is used for this experiment to obtain the sizes of particle distribution in
soil sample that we are testing. According to the British standard 1377-2 the experiment must
be must carried out on a dried sample. Purpose of this experiment is to find the grain size and
distribution. This experiment contains 12 different type of sieves with different sieve aperture
sizes, each can hold materials that is smaller than sieve aperture size. The mechanical shaker
is set to shake the sieves for about 12 minutes according to the British standard.
Carrying experiment
According to British Standard the sample must be around 6 kg
Dried sample to be used for the experiment
Riffle tray is used to ensure the materials of the sample can go through sieves
Stack of sieves are used for the mechanical shaker process
Sieves are properly cleaned and weighted
Putting stack of sieves in order starting from large aperture to small
Then stack of sieves including pan and tray are placed on the mechanical shaker
Mechanical shaker is set to run for 12 minute
Then sieves are removed and one by one and weighed with material in it
The data then recorded
Then the sample are returned back to riffle box to weight
Therefore calculating the loss of sample.
