Match the type of test (List 1) with the objective of the test (List 2). List 1 A. Standard Penetration test B. Hydrometer test C. Proctor test D. Vane test List 2 1. Grain size analysis 2. Shear strength 3. Bearing capacity 4. Compaction
(i) The Standard Penetration Test (SPT) is most popular and economical test used to determine the surface information, both on land and offshore. And alsowidely used to obtain the bearing capacity of soil. (ii) Hydrometer test is carried out to quantitatively determine the Grain Size analysis /Particle distribution for soil particles of size smaller than 75 microns. (iii)The proctor compaction test is a laboratory geotechnical testing method used to determine the soil compaction properties, specifically, to determine the optimal water content at which soil can reach its maximum dry density. (iv)The laboratory vane test used for the measurement of shear strength of cohesive soils, is useful for soils of low shear strength (less than 0.3 kg/cm ) for which triaxial or unconfined tests can not be performed. The test gives the untrained strength of the soil. Hence option(a) is correct.
