The liquid limit test of soil is a laboratory test used to measure the liquid limit of soil and its consistency when it is wet. This test is a part of atterberg limits test with plastic limit test as the other part.Liquid limit is defined as the water content at which a soil changes from a plastic state to a liquid state.The test is performed by a device called a Casagrande apparatus…
It is extremely difficult and impractical to prevent liquefaction of soil in the field when the susceptible zone extends to a large depth. It is generally best not to construct buildings and other structures at sites prone to liquefaction. Because the remediation of the…
We know that soil clay or sand is capable of withstanding heavy loads but is subjected to settlement, consolidation and deformation, which if not controlled, result in shear failure or an ultimate collapse of the structure. Actually it is a known fact that while mixing…
Depending on the amount and type of constituents used in soil cements; it is available in many forms and types in local areas. Some of them are as follows :-
1. Cement Modified Soil (CMS)2. Full-Depth Reclamation (FDR)3. Soil-Cement Base (SCB)4. Cement-Treated base (CTB)Cement Modified Soil (CMS)
If the mixture of soil and cement have relatively low cement content that normal soil-cement than…
Soil Cement is a low cost paving material when used as a base in the pavements for protection of subgrade, or used as a facing material for earth fill dams where suitable riprap is not available, or used as a bedding of drainage concrete heavy pipes, or is also used as slope…
Foundation substructures are structural members used to support walls and columns to transmit and distribute their loads to the ground.
“Footing is the lowest part of the structure that distributes the load on a larger area to avoid any shear or axial failures of the…
What are Stresses in Soil, Over burden Pressure, Total Stress, Effective Stress, Pore water Pressure
August 2, 2015
The Structural loads are supported on soil through foundations. These loads produce stresses and resulting strains or deformations in the soil below the foundation. The deformation in the vertical direction is usually termed as settlement, which occurs due to the vertical stresses.Stresses in a Soil MassThe stresses which produce excessive deformations are termed as failure…
