For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at 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.

This void content depends on grading as well as particle shape and texture. For the individual size fractions Test Method Bthe mean percent void content is calculated using the results satm tests of each of the three individual size fractions. Please first verify your email before subscribing to alerts.

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. Please first log in with a verified email before subscribing to alerts. Uncompacted void content is calculated as the difference between the volume of the cylindrical measure and the absolute volume of the fine aggregate collected in the measure.

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. 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.

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. Request Quote Client Login. Already Subscribed to this document.

A sample consisting of single-size particles will have a higher void content c11252 a graded aatm. 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.

However, Test Method B provides additional information concerning the shape and texture characteristics of individual sizes. For more information, contact: Uncompacted void content is calculated using the bulk dry specific gravity of the fine aggregate.

ASTM C1252 – 17

A decrease in void content results is associated with more rounded, spherical, or smooth-surfaced fine aggregate, or a combination thereof. You may delete a document from your Alert Profile at any time. 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:. An increase in void content by these procedures indicates greater angularity, less sphericity, rougher surface texture, or combinations thereof.

This standard is also available to be included in Standards Subscriptions. Need more than one copy? 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.

Referenced Documents purchase separately The documents listed below are referenced within the atsm standard but are not provided as part of the standard. For this test method, each size is tested separately. 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.

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.

Historical Version s – view previous versions of standard. If the type of rock or minerals, or its asym, 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. The effectiveness of these 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.

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.
