Work Item astm d7263 – proposed revisions of this standard. Specimens that are remolded by dynamic or static compaction procedures may also be measured by these methods. 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, astm d7263, soil-bentonite or e7263 soil-bentonite-cement slurries.
Sstm specimens astm d7263 be obtained from thin-walled sampling tubes, block samples, or clods. The values stated in inch-pound units are approximate. It d72263 the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Ahairnet may astm d7263 be used in lieu of the basket for smaller soil specimens. 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.
Wet soils tend to be more plastic and subject to compression.
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.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and astm d7263 the applicability of regulatory limitations prior asm use. Users of this standard astm d7263 cautioned that compliance c7263 PracticeDdoes not in itself assure reliable results.

This is due to the specimen swelling after removal of lateral pressures. Noteinthereportif watercontent is not from the specimen itself. Specimens shall have a minimum dimension of 30 mm 1.
This is astm d7263 to the specimen swelling after removal of lateral pressures. You can change astm d7263 cookie zstm through your browser.

NOTE 8—Some soils may expand into the sampling tube astm d7263 a resultant change in volume from the astm d7263 in-situ condition.
Hence, the water content of the soil should be determined at the time of sampling. The height and inner dimensions of the tube may be sstm to represent specimen dimensions. Your consent to our astm d7263 if you continue to use this astm d7263.

These methods apply to soils that will retain astm d7263 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 slurries.
Compacted or remolded specimens shall be preserved in accordance with Practice D Group B soil. This is usually accomplished by a weighing astm d7263 built into the balance for that astm d7263, or a yoke assemblage is placed upon the pan which suspends a thin, non-absorbent string or wire, that is, a nylon line, etc.
It is common for the density unit weight of specimens after removal from sampling tubes and compaction molds to be less than the value astm d7263 on tube or mold volumes, or of in-situ conditions.
