Uncompacted voids in aggregates (ASTM C )

When measured on any aggregate of a known grading, void content provides an indication of that aggregate’s angularity, sphericity, and surface texture compared with other fine aggregates tested in the same grading.

A decrease in void content results is associated with more rounded, spherical, or smooth-surfaced fine aggregate, or a combination thereof.

Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void content determinations: The astk aggregate is struck astn and its mass is determined by weighing.

Two runs are made on each sample and the results are averaged. This standard is not included in any packages.

In general, high void content suggests that the material could be improved by providing additional fines in the fine aggregate or more cementitious material may be needed to fill voids between particles.

If the document is revised or amended, you will be notified by email. Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void content determinations We have no amendments or corrections for this standard.

Therefore, use either one method or the f1252 as a comparative measure of shape and texture, and identify which test method has been used to obtain the reported data.

Test Method C does not provide an indication of shape and texture directly if the grading from sample to sample changes.

Historical Version s – view previous versions of standard. Aggregate testing Lab Services: When void content is measured on an as-received fine-aggregate grading, it can be an indicator of the effect of the fine aggregate on the workability of a mixture in which it may asmt used.

For this test method, each size is tested separately. 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.

As the voice of the U. Subscription pricing is determined by: A sample consisting of single-size particles will have a higher void content than a graded sample.

Uncompacted void content is calculated using the bulk dry specific gravity of the fine aggregate. However, Test Method B provides additional information concerning the shape and texture characteristics of individual sizes. Aggregate testing Back to Results Print.
