Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void content determinations 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 c152 it may be used.

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. Need more than one copy? Test Method C does not provide an indication of shape and texture directly if the grading from sample to sample changes. If the type of rock or minerals, or its porosity, in any of the size fractions varies markedly it may be necessary to determine the specific gravity of the size fractions used in the test.

This standard is also available to be included in Standards Subscriptions. This standard is not included in any packages. 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.

The void content is actually a function of the volume wstm each aetm fraction. However, Test Method B provides additional information concerning the shape and texture characteristics of individual sizes.

Typically, the material used 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. The fine aggregate is struck off and its mass is determined by weighing. If the document is revised or amended, you will be notified by email. 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.

We have no amendments or corrections for this standard. Two runs are made on each sample and the results are averaged.

For a graded sample Test Method A or Zstm Method C the percent void content is determined directly, and the average value from two runs is reported. 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. 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 ashm to fill voids between particles.

Uncompacted voids in aggregates (ASTM C )

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:. Standards Subsctiption may be the perfect solution. An increase in void content by these procedures indicates greater angularity, less sphericity, rougher surface texture, or combinations thereof.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. For the individual size fractions Test Method Bthe mean percent void content is calculated using the results from tests of each of the three individual size fractions.

We have no document history for this standard. For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at The effectiveness of ast, test methods of determining void content and its relationship to particle shape and texture depends on the relative density specific gravity of the various size fractions being equal, or nearly so.

Uncompacted void content is calculated using the bulk dry specific gravity of the fine aggregate. 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. Add to Alert PDF. A decrease in void content results is associated with more rounded, spherical, or smooth-surfaced fine aggregate, or a combination thereof.
