Question

Relation between water content and compression index

Answer 1

Explanation:

Foundation of any structure constructed on the

compressible soil layer leads to its consolidation

settlement. The rate of consolidation settlement is

related to the compression index Cc or coefficient of

volume change mv. For design consideration,

knowledge of the rate at which the compression of

the soil takes place is essential. The soil behavior is

an important element which always affected in the

civil engineering. The soil properties such as

plasticity characteristics, compressibility or strength

parameter always affect the design in the

construction. The suitability of a soil for a particular

situation should be determined based on itsengineering properties and not on field observation or

property similarity of other soils. The determination

of consolidation properties from consolidation tests is

expensive, cumbersome and time consuming process,

since it takes a more than 3 weeks to complete a

typical consolidation test. A lot of knowledge,

experience and skill are required on the part of the

Engineer to interpreting the results for field

application. Because of these reason, several studies

have been made in the previous researchers to predict

the compression index from index properties, which

are relatively simple to determine and take lesser

time to obtain the result from the laboratory.
