Testing equipment for ASTM C | Matest

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. As the voice of the U. Typically, the material used to make up the standard graded sample can be obtained asstm 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.

Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void content determinations:. Need more than one copy? An increase in void content by these procedures indicates asrm angularity, less zstm, rougher surface texture, or combinations thereof.

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.

This standard is also available to be included in Standards Astj. For more information, contact: 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.

For the individual size fractions Test Method Bthe mean percent void content is calculated using the c12522 from tests of each of the astk individual size fractions. You may delete a document from your Alert Profile at any time.

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: 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.

Request Quote Client Login. See the Section 9 for the grading. This standard is not included in any packages. 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.

Test Method C does not provide an indication of shape and texture directly if the grading from sample to sample changes. 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.

For this test method, each size is tested separately. Please first verify your email before subscribing to alerts. Standards Subsctiption may be the perfect solution. 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. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

ASTM C1252 – 17

The fine aggregate is struck off and its mass is determined by weighing. However, Test Method B provides additional information concerning the shape and texture characteristics of individual sizes.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the ast of regulatory limitations prior to use. A sample consisting of single-size particles will have a higher void content than a graded sample.

Uncompacted void content is calculated using the bulk dry specific gravity of the fine aggregate. Proceed to Checkout Continue Shopping. The void content is actually a function of the volume of each size fraction.

Two runs are made on each sample and asstm results are averaged. A decrease in void content results is associated with more rounded, spherical, or smooth-surfaced fine aggregate, or a combination thereof.

Your Alert Profile lists the documents that will be monitored. We have no document history for this standard. 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. We have no amendments or corrections for this standard.
