In order to directly measure the submergedmassofthewetsoilandwax,thebalancemusthave been previously balanced tared to zero with the astm d7263 basket completely submerged in the container of water. Ahairnet may also be used in lieu of the basket for smaller soil specimens.
These methods apply to soils that will retain their shape during astm d7263 measurement process and may also apply to other materials such astm d7263 soil-cement, soil-lime, soil-bentonite or solidified soil-bentonite-cement slurries. Since soilvolumeshrinkswithdryingofswellingsoils, bulkdensity will vary astm d7263 moisture content. This is usually accomplished by a weighing hook built into the balance for that purpose, or a yoke assemblage is placed upon the pan astm d7263 suspends a thin, non-absorbent string or wire, that is, a nylon line, etc.
Specimens are usually cubical or cylindrical in shape. Specimens shall have a minimum dimension of 30 mm 1. Wet soils tend to be more plastic and subject to compression.
Work Item s – proposed revisions of this standard. Link to Active This link will always route to the current Active version of astm d7263 standard. Acontainerheatedbyhot water, preferably thermostatically controlled, is satisfactory.
This is due to the specimen axtm after removal of lateral pressures. NOTE 1—The quality of the result produced by this standard is dependent on the competence of astm d7263 personnel performing it and the suitability of the aztm and facilit ies used.
Specimens that are remolded by dynamic or static compaction procedures may also be measured by astk methods. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Astm d7263 results depend on several factors; Practice Dprovides astm d7263 means astm d7263 evaluating some of these factors. Specimens that are remolded by dynamic or static compaction procedures may also be measured by these methods. Referenc Referenced ed Documents 2.

These methods apply to soils that will retain their shape during the measurement process and may also apply to other materials such as soil-cement, soil-lime, soil-bentonite or solidified d763 slurries.
Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. Since moisture content is variable, moist soil density provides astm d7263 useful information except to estimate the weight of soil per s7263 volume, for example, pounds per cubic yard, at the time c7263 sampling.
Dry density values are usually used in conjunction wit h compaction curve values Test Methods DandD Intact specimens may be obtained from thin-walled sampling tubes, astm d7263 samples, or clods. Re-entrant a ngles should be avoided, and any cavities formed by l arge particles being pulled out should be patched carefully with mat erial from the trimmings.

This is due to the specimen swelling after removal of lateral astm d7263. Astj or remolded specimens shall be preserved in accordance with Practice D Group B soil. Dry density values are usually used in conjunction with compaction curve astm d7263 Test Methods Astm d7263 and D Not Logged In Member?: Noteinthereportif watercontent is not from the specimen itself.
Dry density measurements are al so useful for determiningdegreeofsoilcompaction. It is common for the density unit weight of specimens after removal from sampling tubes and compaction molds to be less than the value based on tube or mold volumes, or of in situ conditions.
The values stated in inch-pound units are approximate. Work Item s – proposed revisions of this standard.
It is the responsibility of the user of this standard to establish appropriate safety, health, and d2763 practices and determine the applicability of regulatory limitations prior to use. The height and inner dimensions of the tube may be taken to represent specimen dimensions. NOTE 5—Maintainwaterbathtemperatureandsubmergedbasketdepth the same as when calibrated astm d7263 z eroed. If required, astm d7263 the specimen to a fairly regular shape.
When the sample condition permits, a vertical trimming lathe may be used to reduce cylindrical specimens to a uniform diameter. Link to Active This link astm d7263 always route to the current Active version of the standard.
It can bepeeled off after astm d7263 break is made in the wax surface.
The basket shall be constructed to prevent trapping air when astm d7263 is submerged. Referenced Documents purchase separately The documents listed astm d7263 are referenced within the subject standard but are not provided as part of the standard.

Make sure that the specimen and basket is fully submerged, and that the basket is not astm d7263 the sides or bottom of the container.

Since soil volume shrinks with drying of swelling soils, bulk density will vary with moisture content. NOTE 7—Coresamplingmightbedifficultorimpossibleingravelly or hard dry soils.
