1.1 This method of test is to determine a weight per cubic foot of sand to be used in soil density determinations, and the volume of the sand to fill the funnel and baseplate on the sand cone apparatus. 1.2 This test method may involve hazardous materials, operations, and equipment.
18-11-2010· In principle sand cone replacement is more accurate than troxler when carryout field density tests.However sand replacement method is slow as it involve more activities.In order to use troxler you are required to calibrate the troxler on site in line with the sand replacement method.First step carryout a sand replacement and the same time just short from hole carryout field density test by the ...
Sand Cone Test Testing objectives: Determine the in-situ density of natural or compacted soils using sand replacement method. Need and Scope: The main application of this test is the cases like embankment and pavement construction, this is basically a QC test or quality control test where certain degree of compaction is required.
24-02-2021· 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 a pouring cone at its base. There is a shutter between the cylinder and the cone. The cylinder is first calibrated to determine the unit weight of sand.
Precaution of sand cone test The test sand should be dry and fine enough to fill the excavated portion uniformly. The inner lateral surface area of the hole should be made uniform before filling the test sand. The weight of sand should be taken correctly. The base place should be fixed at the ...
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.
