For soils, such as hard soil or granular soil, where core cutter method cannot be applied, sand replacement method is used for the determination of unit weight of soil in its natural state. For this test to perform we will be needing a calibrating sand which passes through 1 …
14-04-2017· Aim: Determination of in-situ dry density by sand replacement method Theory. A hole of stated measurements is dug in the ground. The weight of the dug soil is ascertained. The size of the hole is ascertained by filling it up with clean, unvarying sand whose dry density ( ) is computed distinctly by standardization.The size of the hole is equivalent to the weight of the sand packed in the hole ...

INTRODUCTION 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. The moisture content of the soil vary from time to time and hence the field density also, so it is required to report the test result in terms of dry density.
This test is done to determine the in-situ dry density of soil by sand replacement method as per IS: 2720 (Part XXVIII) – 1974. The apparatus needed is i) Sand-pouring cylinder conforming to IS: 2720 (Part XXVIII) -1974 ii) Cylindrical calibrating container conforming to IS: 2720 (Part XXVIII) – 1974
Sand replacement method is known to be better than the core-cutter method because it can be used in any type of soil and the results are far more appropriate than the approximate values of the core-cutter method. New questions in Science. Two important properties of gases

The sand cone method is used for field density test in highway construction. In the field, the dry density test is performed to check the compaction of layers. Compaction is most beneficial for the preparation of sub base grade and different pavement layers and in the production of embankment in order to increase the steadiness and to lower settlement .

The relationship that can be established between the dry density with known moisture content is as follows: Sand replacement method (standard method, but does not apply to fill a big stone embankment and other porous materials, holes or large degree of compaction test) is the use of the basic principles of particle size 0.30 ~ 0.60mm or 0.25 ~ 0.50mm uniform clean sand, from the the ...
In sand replacement method, a small cylindrical pit is excavated and the weight of the soil excavated from the pit is measured. Sand whose density is known is filled into the pit. By measuring the weight of sand required to fill the pit and knowing its density the volume of pit is calculated.
Sand replacement density (SRD) tests are used to measure the in-situ density of natural or compacted soils using sand pouring cylinders. The in-situ density is typically used for highway or pavement design purposes to estimate the relative density of base course or subgrade materials.

Core Cutter Method of Field Density test is conducted in the field to know whether the specified compaction is achieved or not.. In certain cases, it is necessary to determine the density of soil either as it exists naturally in the ground or as it may be compacted in the fill.. In the former case, this density of soil in place may be used to estimate the comparative strength of the soil.
