It is the
In-situ Density Determination by Sand Replacement Method Lecture Note 7 – (Thursday 03-04 ... • Sand cone apparatus which consists of a one-gallon plastic bottle with a metal cone attached to it. • One-Gallon plastic can with cap. • Balance sensitive to 1 g. ... Name any two other methods for obtaining the In-situ density of soils? 10
In-place (In-situ) density of a soil Several different methods are used to determine the in-situ density of a soil; • Rubber balloon method • Sand-replacement (sand cone) method, • Core cutter method 4 Core cutter method • Nuclear moisture-density meter method.
Dry density of soil is determined by first determining the in-situ density of soil and then calculating dry density by using the equation. Yd = Y/1+m . where Y d = dry density of soil . g = Bulk density or insite density . m = moisture content or water content. The in-situ density is determined by the following methods: (i) Sand replacement method
Drying can for water content determination Balances sensitive to 1g and 0.01g Drying oven with temperature ranges from 1050C to 110 0C Desiccator THEORY: The sand pouring cylinder test is used to determine the soil density in the field (in-situ density) and to control the results of the field compaction in earth embankments, road fills and ...
Procedure To Determine The In-Situ Dry Density Of Soil By Sand Replacement Method . A. Calibration of apparatus a) The method given below should be followed for the determination of the weight of sand in the cone of the pouring cylinder:
density and unit weight of soils using a sand cone apparatus. 1.2 This test method is applicable for soils without appre-ciable amounts of rock or coarse materials in excess of 11⁄2 in. (38 mm) in diameter. 1.3 This test method may also be used for the determination of the in-place density and unit weight of undisturbed orin situ
Dec 12, 2013· Sand replacement 1. Sand replacement test 2. Objective Student should be able to : Determine the in situ density of natural or compacted soils using sand pouring cylinders. 3. Theory By conducting this test it is possible to determine the field density of the soil.
SAND REPLACEMENT (INSITU-DENSITY) METHOD (IS 2720-PART-28-1974) Reaffirmed-2010 THEORY: The in-situ density is defined as the bulk density of soil measured at its actual depth. By conducting this test, it is possible to determine the field density of the soil. The moisture content is likely to vary from time and hence the field density also.
The Sand Cone Method is a sand replacement method for determining the field unit weight or the in-situ density of natural or compacted soil. There are three standard procedures used for ...
The field density test of soil is conducted in the field to know whether the specified compaction is achieved or not. Normally Sand Replacement Method is adopted for this purpose. Sand Replacement Method is also known as Sand Cone Method. The apparatus used in this field density test consists of a sand pouring cylinder, with pouring cone at its ...

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.
1.3 This test method may also be used for the determination of the in-place density and unit weight of intact or in situ soils, provided the natural void or pore openings in the soil are small enough to prevent the sand used in the test from entering the voids. The soil or other material being tested should have sufficient cohesion or particle attraction to maintain stable sides on a small ...
In Situ Density – Sand Cone Replacement method 4.1 Aims and Objectives The aim of this experiment is to determine the bulk and dry density of soil in situ that is on the site by the sand cone replacement method. 4.2 Introduction The sand cone apparatus is used to determine the in-situ density of any soil that can be excavated to a stable ...
FIELD OR IN-SITU DENSITY TEST BY SAND REPLACEMENT METHOD Aim: To determine the in-situ density of soil by Sand Replacement Method. Reference IS Code: IS 2720- Part XXVIII Materials and Equipment: 1. Standard sand 2. Sand pouring cylinder 3. Calibrating container 4. Metal tray 5. Balance accurate to 1 gm 6. IS sieves of sizes 600 micron and 300 ...
The verification of the degree of compaction can be determinate on site by a simple procedure consisting essentially in removing and weighing a part of compacted soil and replacing in the hole with sand by a simple apparatus recording the volume of sand and then calculating the density of the removed soil.
cutter method and the sand replacement method. 6.2 Sand Replacement Method 6.2.1 Introduction. The sand replacement method is the most widely used in-situ density test. Although the test takes slightly longer to perform than some other in-situ density .
Dec 26, 2016· Field Density Test ( Sand Cone Method): The sand cone method is one of the most common methods that are used for field density test in highway construction. The dry density test is carried out in the field to check the compaction of the layers.
FIELD DENSITY TEST. SAND REPLACEMENT METHOD. OBJECTIVE Determine the in situ density of natural or compacted soils using sand pouring cylinders. ... and remove the cylinder carefully. Weigh the sand collected on the glass plate. Its weight(W 2) gives the weight of sand filling the cone portion of the sand pouring cylinder.
Hoping that the above have helped the Quality Engineers or civil Engineers to better understand how the compaction test or In-situ density test using the sand replacement method is .
ADVERTISEMENTS: It is often required to determine the density of soil in the natural state (in-situ density). There are several methods available for the determination of in-situ density. Two commonly used methods are: 1. Core Cutter Method 2. Sand Replacement Method. 1. Core Cutter Method: Core cutter method is used to determine the in-situ density [.]
