Active Risk Management
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 measured on any aggregate of a known grading, void content provides an indication of that aggregate’s angularity, sphericity, qstm surface texture compared with other fine aggregates tested in the same grading.
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. Your Alert Profile lists the documents that will be monitored. A sample consisting of single-size particles will have a higher void content c152 a graded sample.
However, Test Method B provides additional information concerning the shape and texture characteristics of individual sizes. It is ast, responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Already Subscribed to this document. As the voice of the U. Subscription pricing is determined by: 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.
ASTM C1252 – 17
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: Link to Active This link will always route to the current Active version of the standard. 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.
The fine aggregate is struck off and its mass is determined by weighing.
Uncompacted voids in aggregates (ASTM C )
If the document is revised or amended, you will be notified by email. A nominal mL calibrated cylindrical measure is filled with fine aggregate of prescribed grading by allowing the sample to flow through a funnel from a fixed height into the measure.

Aggregate testing Lab Services: A decrease in void content results is associated with more rounded, spherical, or smooth-surfaced fine aggregate, or a combination thereof. For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void content determinations In general, high void content suggests that the material could be improved by providing additional fines in the aetm aggregate or more cementitious material may be needed to fill voids between particles.
Historical Version s – view previous versions of standard. Aggregate testing Back to Results Print. When measured c122 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.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Testing equipment for ASTM C | Matest
This void content depends on grading as well as particle shape and texture. For this test method, each size is tested separately. Uncompacted void content is calculated using the bulk dry specific gravity of the fine aggregate.
Test Method C does not provide an indication of shape and texture directly if the grading from sample to sample changes. Request Quote Client Login.
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. Please first log in with a verified email before subscribing to alerts. Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void content determinations:.
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. 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. For more information, contact: The void content is actually a function of the volume of each size fraction.
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. Standards Subsctiption may be the perfect solution.
