4.3 If the soil contains sand or larger size particles, provision must be made to separate the minus No. 40 (0.425 mm) material for testing despite the possibility that drying may alter the characteristics of some soils. The fine fraction of granular soil is
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.
aggregate (natural sand of 4.74mm maximum size), coarse aggregate (max size below 20mm) and addition of 10%, 15% and 20% of plastic waste as sand replacement. Their test results indicate sharp decrease in slump with increasing the percentage of plastic, this decrease was attributed to the presence of angular and non uniform plastic particles.

9.3.3.10 Sand replacement test. The sand replacement method is used to determine in-place density. The sand replacement method of determination of in situ density uses a sand-pouring cylinder, cylindrical calibrating container, tray with a central circular hole, and a chisel. Determination of field density using the sand replacement method ...
If sand is salvaged from holes in compacted soils after carrying out the test, it is advisable to sieve, dry, and store this and again before it is used in further sand replacement tests. Calculations: The in-situ density is calculated as explained below: i. Bulk Density of Sand: Bulk density of sand is calculated from – γ sand = W s / V 1 ...

[Show full abstract] In this study, compressive strength of 4-inch concrete cubes has been determined to see the variation in strength of concrete with the partial replacement of cement by RHA ...
The results of this study can be used to reevaluate and revise the test method for soil density by the sand replacement method. Do you want to read the rest of this article? Request full-text
7) Reset the base plate over the test hole and invert the apparatus onto the base plate and open the valve to allow sand to flow into the test hole. When the sand flow stops, shut off the valve and remove and weigh the apparatus. Do not tap or vibrate the apparatus during this process. The weight obtained is entered on Form IT 625 Line 6 (Final Wt.
Sep 22, 2017· 4. Now place the sand cone on the test hole with the help of the base plate and allow the sand to run by opening the control valve. 5. When the sand stops running, close the valve and weight the cone with the existing sand. Finally, calculate the dry density of the soil by given below formula. If the test fails, compact and perform the test again.

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 Engineer's 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.
performance test: A constant-current or constant-power capacity test made on a battery after it has been in service, to detect any change in the capacity. polarization: The shift in the potential of an electrode, or the voltage of a cell/battery, from the open- circuit value, brought about by the flow of current.
Abstract- This experimental study presents the variation in the ... From test results it was found that the maximum compressive strength is obtained only at 50% replacement at room temperature and net strength after ... replacement of sand from 0% to 100% in step of 10%.
The various results which indicate the effect of replacement of cement by metakaolin on concrete are presented in this paper to draw useful conclusions. The results were compared with reference mix. Test results indicate that use of replacement cement by metakalion in concrete has improved performance of concrete up to 15%.

The test conducted at the field to check the density of soil to ensure whether it has been compacted well as . per the requirements is known as Sand Replacement Test. They are otherwise known as Field Density Test or FDD Test of sand. Density / Unit Weight – The unit weight of the material is defined as Mass per Volume (M/V)
May 25, 2015· A sand-cone method is commonly used to determine the density of compacted soils. The density of the compacted soil calculated from the sand-cone method could be correct, provided the calibration container has approximately the same size or volume and allows the sand to fall to approximately the same height as a test hole in the field.
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 tests, the test may be .
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 ...
