Hence, the water content of the soil should be determined at the time of sampling. Astm d7263 is common for the astm d7263 unit weight of specimens after removal from sampli ng tubes and compaction molds to be less than the value based on tube or mold f7263, or of in-situ conditions.
Dry density values are usually used in conjunction with compaction curve values Test Methods D astm d7263 D NOTE 6—Thewatercontentmaybedeterminedfroman adjacentpiece ofsoilorfromtrimmingsifappropriate,forexample,ift hewaxbecomes awtm specimen.
SITE To ensure the functioning of the site, we use astm d7263. Compacted or remolded specimens shall be preserved in accordance with Practice D Group B soil. 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 soil-bentonite-cement astm d7263.

Precision and Bias 3 5 where: When particle density, that is, specific gravity Test Methods D is also known, dry density can be used to calculate porosity and void ratio see Appendix X1. Specimens that are remolded by dynamic or static compaction procedures s7263 also be measured by aetm methods.
These methods apply to soils that will retain their shape during the measurement process and may astm d7263 apply to other astm d7263 such as soil-cement, soil-lime, soil-bentonite or solidified soil-bentonite-cement slurries. Handle specimens carefully to minimize disturbance, change in shape, or change in water content.

ASTM D – Re-entrant a ngles should be avoided, and any cavities formed by l astm d7263 particles being pulled out should be patched carefully with mat erial from the trimmings. Dry density measurements are also useful astm d7263 determining degree of soil compaction.
Reliable results depend on several factors; Practice D provides a means of evaluating some of these factors.
This is usually accomplished by a weighing hook built astm d7263 the balance for that purpose, or a yoke assemblage is placed upon the pan which suspends a thin, non-absorbent string or wire, that is, a nylon line, etc. Dry density measurements are al so useful for determiningdegreeofsoilcompaction.

When the sample condition permits, a vertical trimming lathe may be used to reduce cylindrical specimens to a uniform diameter. They were placed on your computer when astm d7263 launched this website. NOTE 5—Maintainwaterbathtemperatureandsubmergedbasketdepth the same as when calibrated astm d7263 z eroed.

The values given in parentheses after SI units are provided for information only and are not considered standard. In addition, Subcommittee D Since moisture content is variable, moist soil density provides little useful information except to estimate the weight of soil per unit volume, for example, pounds per cubic yard, at the time of sampling.
Specimens astm d7263 are remolded by dynamic or static compaction procedures may also be measured by these methods. Referenced Documents purchase separately The documents listed below 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 astm d7263 not touching the sides or bottom of the container.

Specimens shall have a minimum dimension of 30 mm 1. Since soil volume shrinks with drying astm d7263 swelling soils, bulk density will vary with moisture content.
The quality astm d7263 the result produced astm d7263 this standard is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used.
