Introduction to ASTM D854
The ASTM D854 test method is used for the determination of gravity of tropical soils, highly plastic fine-grained soils, and soils consisting of halloysite and oven-dry specimens. The mass of the pycnometer and water at the test temperature are also used for the assessment of the specimen. In the ASTM D854 test method, the specific gravity of soil solids is used to determine the associations of soils, the void ratio, and the degree of saturation. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM D854 tests for our clients.
ASTM D854 Test Method
| Gravity measurement | In ASTM D854, the density of the solid soil is determined by multiplying its specific gravity by the density of the water. It is verified that the pycnometer is within 0.06 g. |
| Evaluation | It allows the assessment of precise measurements of the specimen mass and the mass of selected liquid and the use of standardized procedures. |
ASTM D854 Test Specimen
| Specimen Detail | In the ASTM D854 test method, the test specimen is moist or dry soil and it is representative of the soil solids that pass the 4.75-mm in a sieve. |
| Specimen Size | The mass of the soil solids is separated by its specific gravity, yielding four significant digits. The combination of soil solids and water makes slurry, which is not an extremely viscous fluid in the drying process. |
ASTM D854 Test Result
The ASTM D854 test method is helpful for determining the gravity of soil solids at the test temperature, which is determined either by the density of the soil solids or the density of water at the standard test temperature by a pycnometer.
ASTM D854 Related Tests
The ASTM D854 test method is related to ASTM D2216, which is used to test the determination of the water content of soil and rock by mass, and ASTM D5550, which tests the gravity of solid soils by the gas pycnometer.
