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.
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 ...
Scope* 1.1 This test method may be used to determine the in-place density and unit weight of soils using a sand cone apparatus. 1.2 This test method is applicable for soils without appreciable 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 ...
Invert the sand cone filled with sand, and seat the funnel in the recess of the base plate. Open the valve fully and allow the sand to flow until the sand stops flowing. Close the valve sharply, remove the apparatus, and determine the mass of the apparatus and the remaining sand (m2).
In geotechnical engineering practice, three methods are usually used to determine the in-situ density of natural or compacted soils: (a) the sand-cone method; (b) the rubber-balloon method; and (c) the nuclear method. The sand-cone method is relatively simple and inexpensive when compared with other methods. As a result, it has been commonly ...
The document describes a laboratory experiment to determine soil properties using the sand cone test method. It includes the objectives, apparatus, theory, procedure, observations and calculations for the test.
1.1 This test method may be used to determine the in-place 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.
