Determination of Maximum Dry Density and Optimum Moisture Content of Soil -IS:2720 (Part VII)
Relationship between maximum dry density of the soil and the water content can be obtained by soil compaction test. This relationship helps in determining the optimum water content at which maximum dry density of soil can be attained through compaction.
Determination of Dry Density of Soil by Water Displacement Method
Water displacement test method is used to determine the dry density of soil. It is suitable for evaluating in-place dry density of cohesive soil due to the nature of specimen required. The soil sample should be trimmed to obtain a ...
Determination of In-situ Soil Dry Density by Sand Replacement Method
The sand replacement test method is used to determine in situ dry density of soil. The procedures, materials, equipment, and specifications of this test is based on the Indian Standard (IS 2720 part 28). This test is of significant importance ...
Double Shear Test on Mild Steel
Double shear test is used to determine the shear strength (ultimate shear stress) of the mild steel specimen. Universal testing machine (UTM) is used for performing double shear test. There are two types of UTM namely: screw type and hydraulic ...
Bulk Density and Void Percentage Test for Aggregates
The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29/C29M-17a, IS: 2386 (Part 3) – 1963, or BS 812-2:1995. The procedure provided in this article is based ...
Variable Head Permeability Test of Soil- Purpose, and Procedures
Variable head permeability test is one of several techniques by which the permeability of soil is determined. It is used to evaluate the permeability of fairly less previous soil. Permeability is the measure of the ability of soil to allow ...
