Sand cone test is performed to test the field density in highway or road construction. Actually it is the simplest way to check the compaction of the different layers below the surface of the ground.
To use this online calculator for Field Density in Sand Cone Method, enter Weight of Total Soil (W t) & Volume of Soil (V) and hit the calculate button. Here is how the Field Density in Sand Cone Method calculation can be explained with given input values -> 4 = (80/20) .
FIELD DENSITY BY THE SAND CONE METHOD (A Modification of AASHTO Designation T 191) SCOPE 1. (a) This method is used to determine the density of compacted soils or aggregates by determining the weight and moisture content material removed from a test hole and measuring the volume of the test hole.
The sand cone method is a commonly used in-situ test to determine the field density and dry density of soil. It involves using a calibrated sand cone apparatus, which includes a jar filled with dry sand, a cone with a valve, and a base plate.
Calculation For FDT Test: The volume of the hole = Mass of sand in hole/Density of used sand. Wet density = Mass of wet excavated soil/Volume of hole. Dry density = Wet density × 100%/ Moisture content of soil + 100. Degree of compaction = Dry density × 100%/Maximum dry density. Also Read – Slump Test Of Concrete. Compaction Factor Test ...
ASTM D1556: Standard Test Method for Density and Unit Weight of Soil in Place by the Sand Cone Method. Apparatus: 1- Sand-cone density apparatus, consisting of sand container, sand cone (funnel), and base plate. 2- Small digging tools (e.g., shovels, trowels). 3- Balance. 4- Large sealable plastic bag or airtight container. Fig.1—Sand cone ...
With the calculations of the Bulk Density of the calibration sand and the Cone Correction Factor completed, the Technician has all of the information necessary to begin in-place density tests. Using Form IT 625, the procedure for an in-place sand cone density tests on soil is as follows:
