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

Determination of Field Density of soil by drive cylinder (core cutter) method (AASHTO T204 -90)

Knowing the density of soil at field is of utmost importance for a transportation and civil engineer. The Soil under the action of load consolidates and settles due to empty pores and spaces and also due to expulsion of moisture and air within those pores and interstices. The densification of soil is due to removal, … Read more

Determination of field density of soil by Sand Replacement Method

Sand replacement test method is used to determine the field density or in-place density of earth embankments, road fills, sub-grade, sub-base or any of compacted material. This method serves as base upon which one can accept the density of a compacted material to a specified magnitude or to a percentage of maximum unit dry density … Read more

Soil Mechanics Laboratory Manual [PDF] Geotech Engineering Manual

To study about materials is very essential for civil engineers. Civil Engineers deal with variety of materials like concrete, cement, aggregates, soil, bricks and various others that are used to construct or to support some structural load. The ultimate destination of load for any structure is soil. Soil absorbs as well as dissipates the load … Read more
