For more information, contact: Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void content determinations An increase in void content by these procedures indicates greater c252, less sphericity, rougher surface texture, or combinations thereof. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. A decrease in void content results is associated with more rounded, spherical, or smooth-surfaced fine aggregate, or a combination thereof. Two runs are made on each sample and the results are averaged. Proceed to Checkout Continue Shopping. This standard is not included in any packages.

Uncompacted void content is calculated using the bulk dry specific gravity of the fine aggregate. You may delete a document from your Alert Profile at any time. We have no document history for this standard.

Aggregate testing Lab Services: If the document is revised or amended, you will asttm notified by email. Typically, the material qstm to make up the standard graded sample can be obtained from the remaining size fractions after performing a single sieve analysis of the fine aggregate.

Your Alert Profile lists the documents that will be monitored. Subscription pricing is determined by: Standards Subsctiption may be the perfect solution.

See the Section 9 for the grading. 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 be used. For a graded sample Test Method A or Test Method C the percent void content is determined directly, and the average value from two runs is reported. Add to Alert PDF. astmm

The fine aggregate is struck off and its mass is determined by weighing. Therefore, use either one method or the other as a comparative measure of shape and texture, and identify which test method has been used to obtain the reported data.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

This void content depends on grading as well as particle shape and texture. For this test method, each size is tested separately. This standard is also available to be 1c252 in Standards Subscriptions.

Please first verify your email before subscribing to alerts. However, Test Method B provides additional information concerning the shape and texture characteristics of individual sizes.

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

Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void content determinations: Aggregate testing Back to Results Print. We have no amendments or corrections for this standard.

For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at Test Method C does not provide an indication sstm shape and texture directly if the grading from sample to sample changes.
