ASTM C1252 – 17

Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void content determinations It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine c1225 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, and surface texture compared with other fine aggregates tested in the same grading.

Two use graded fine aggregate standard grading or as-received gradingadtm the other uses several v1252 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.

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.

The effectiveness of these test methods of determining void content and its relationship to particle shape and texture depends c12252 the relative density specific gravity of the various size fractions being equal, or nearly so.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Proceed to Checkout Continue Shopping. We have no document history for this standard. 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.

See the Section 9 for the grading. This void content depends on grading as well as particle shape and texture. Please first verify your email before subscribing to alerts.

For more information, contact: Two runs are made on each sample and the results are averaged. Test Method C does not provide an indication of shape and texture directly if the grading from sample asttm sample changes.

The void content is actually a function of the volume of each size fraction. Aggregate testing Back to Results Print. If the type of rock or minerals, or its porosity, in any of the asrm fractions varies markedly it may be necessary to determine the specific gravity of the size fractions used in the test.

However, Test Method B provides additional information concerning the shape and astj characteristics of individual sizes. Aggregate testing Lab Services: This standard is also available to be included in Standards Subscriptions.

Subscription pricing is determined by: 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.

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. 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.

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

For this test method, each size is tested separately. Standards Subsctiption may be the perfect solution. 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 The fine aggregate is struck off and its mass is determined by weighing. 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 aztm 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. As the voice of the U.
