OBJECTIVE
To introduce the
students to the method of making a mechanical grain size analysis of a soil and
presenting the resulting data.
THEORY
Grain size analysis carries much importance in
determination of engineering properties of soil e.g. suitability criteria of soils
(for road, airfield, levee, dam and foundation material), soil water movement,
susceptibility to frost action etc.
The grain size analysis is the attempt to determine
the...

OBJECTIVE:
To
familiarize the students with general method of obtaining the specific gravity
of a mass of any type of material composed of small particles (specifically
soil).
THEORY
A
value of specific gravity is necessary to compute the void ratio of a soil, it
is used in the hydrometer analysis, and it is useful to predict the unit weight
of a soil. Occasionally,...
