Chat OnlineSep 11, 2020 Sand Replacement method is used to find in-situ density of natural or compacted soils. Sand Replacement test for determination of density of soil measure the in-situ volume by sand pouring cylinder. In short, we measure weight of excavated soil from hole and volume of hole. Then density can be easily calculated by dividing weight by volume.

Relative density of a natural cohesionless or compacted soil can be determined in the laboratory by using the stand ard relative density equipment. Principle The relative density of natural or compacted soil can be determined by obtaining the minimum and maximum density of soil in the laboratory and the in-situ density of soil in the field.
Reading time 1 minute 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 and it has been widely used in various construction project

The dry density of the compacted soil or pavement material is a common measure of the amount of compaction achieved during construction. It can be calculated from the field density and field moisture content data therefore, field density or the in-situ density test is an important field control test for the compaction of soil or any other ...
Apr 19, 2013 determine the in situ density of natural or compacted soils using sand pouring cylinder situ dry density of soil by sand replacement specifications for building coarse aggregates on loose bulk density 20mm limestone tonne per m3
Jun 16, 2018 This method covers the determination in situ of the density of natural or compacted soil containing coarse- grained particles which make the test described in 2.1 difficult to perform. It is an alternative to that test for fine- and medium-grained soils and should be used instead of that test for layers exceeding 150 mm, but not exceeding 250 ...
Oct 04, 2014 Here is the procedure on how to do the Compaction test or In-Situ Density test.. 1. Place the metal tray. The technician can now place the metal tray as per the Consultant or Quality Engineers preferred location.As a Quality Engineer, you should make sure that the area to be tested is compacted and within the area submitted in the Inspection Request.
Determining the in situ density of natural or compacted soils using sand pouring cylinders requires simple method of analysis. The in situ density of natural soil is needed for the determination of bearing capacity of soils, for the purpose of stability analysis of slopes, for the determination of pressures on underlying strata for the calculation of settlement and the design of underground structures.
The method is used to determine in situ density for natural or manmade compacted soils, especially in stability analysis of slopes. ... w is the water content and g 0 is the bulk density. The sand pouring cylinder is filled with the clean sand, the initial weight of the cylinder with sand is noted and it will be maintained throughout the test ...
Objective To determine the in-situ density of granular soils using sand replacement method and cohesive soils using core cutter method. Need and Scope The in situ density of natural soil is needed for the determination of bearing capacity of soils, for the purpose of stability analysis of slopes, for the determination of pressures on underlying strata for the calculation of settlement and the ...
Calibration of the cylinder is done to determine the bulk density of the sand to be used for this test. Calibration of the cylinder is completed in the following steps I. Fill the pouring cylinder with clean, free flow sand, passing 600 micron and retained on 300 micron sieve, about 1 cm below the top. Weigh the pouring cylinder with sand.
