ASTM D7263

ASTM D – astm d7263 Specimens that are remolded by dynamic or astm d7263 compaction procedures may also be measured by these methods. Wet soils tend to be more plastic and subject to compression. Not Logged In Member?: How one applies the results obtained using this standard is beyond its scope. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of astm d7263 limitations prior to use. 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.

It is common for the density unit weight of specimens after astm d7263 from sampli ng tubes and compaction molds to be less than the value based on tube or mold volumes, or of in-situ conditions. Your consent to our cookies if you continue to use this website.

This astm d7263 done by placing the specimen in a wire basket hookedontoabalanceandimmersingthebasketandspecimen in a container of water. NOTE 4—Ifoverheatedwaxcomesincontactwiththe soilspecimen,it may cause the moisture to vaporize and form air bubbles under the wax. Specimens are usually cubical or cylindrical in shape. This is due to the specimen swelling after removal of lateral pressures.

Dry density measurements are al so useful for determiningdegreeofsoilcompaction. Acontainerheatedbyhot water, preferably thermostatically controlled, is satisfactory.

Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. Qstm methods astm d7263 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.

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.

When the sample condition permits, a vertical trimming lathe may be used to reduce cylindrical specimens to a uniform diameter. After a specimen is formed, trim if necessary the ends perpendicular to the longitudinal axis, remove the mold, and determine the mass and dimensions of the test specimens inaccordancewith7. Intact specimens may be obtained from thin-walled sampling tubes, block samples, or clods.

Make sure that the specimen and basket astm d7263 fully submerged, and that the basket is not touching the sides or bottom of the container. Handle astm d7263 carefully to minimize disturbance, change in shape, or change in water content.

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 astm d7263 volumes, or of in situ conditions.

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 slurries. In addition, Subcommittee D Howoneappliesthe resultsobtainedusing this standard is beyond its scope. The quality of the result astm d7263 by this standard astm d7263 dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used.

The values given in parentheses after SI units are provided for information only and are not considered standard. Hence, the water content of astm d7263 soil should be determined at the time of sampling. If required, trim the specimen to a fairly regular shape.

NOTE 1—The quality of the result produced by this standard is dependent on the competence of the personnel performing it and the suitability astm d7263 the equipment and facilit ies used. NOTE 8—Some soils may expand into the sampling tube with a resultant change astm d7263 volume from the original in-situ condition.
