16 Σεπ 2020 · Carry the sand cone, base plate, bucket and digging tools to the area to be tested. Drill the soil from a circular hole in the base plate by a coop, spoon, or other suitable digging tool.
8 Ιουν 2024 · The sand cone test illuminates the level of soil compaction—a key factor when laying foundations, paving roads, and other construction projects. While the procedure may seem direct, mastering it requires art and technical know-how.
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.
Using Form IT 625, the procedure for an in-place sand cone density tests on soil is as follows: 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.
To determine the in-place density/unit weight of soils of natural soil. To determine the density and water content of compacted soils. It often is used as a basis of acceptance for compacted soils. ASTM D1556: Standard Test Method for Density and Unit Weight of Soil in Place by the Sand Cone Method.
13 Μαρ 2015 · 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 1 1/2 in. (38 mm) in diameter.
Standar ini menetapkan metode uji densitas tanah di tempat (lapangan) menggunakan alat konus pasir. Peralatan yang diuraikan di sini dibatasi untuk pengujian tanah yang mengandung partikel berbutir dengan diameter tidak lebih dari 50 mm.
