What are the different Methods Used for Geotechnical Soil Testing?

Geotechnical engineers and engineering geologists conduct geotechnical investigations to gather data on the physical characteristics of the rock and soil surrounding a site. This is necessary for designing foundations for structures and repairing damage to earthworks and structures resulting from subsurface conditions. Measurement of the thermal resistivity of soils or backfill materials used for underground … Read more

Determine Liquid Limit of Soil Specimen by Casagrande Method

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 … Read more

Methods of Reducing Soil Liquefaction

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 liquefaction hazard is quite expensive, it would be cost effective only … Read more

What is Soil Cement

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 different construction material would also combine their positives. So Soil … Read more

What are different types of Soil Cement

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 … Read more
