Testing equipment for ASTM C | Matest

An increase in void content by these procedures indicates greater angularity, less sphericity, rougher surface texture, or combinations thereof. This standard is not included in any packages.

For this test method, each size is tested separately. A sample consisting of single-size particles will have a higher void content than a graded sample.

Uncompacted voids in aggregates (ASTM C )

We have no amendments or corrections for this standard. Uncompacted void content is calculated using the bulk dry specific gravity of the fine aggregate. Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size c252 for void content determinations:.

Two use graded fine aggregate standard c12552 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.

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 asmt particles. As the voice of the U. Subscription pricing is determined by: 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.

For Individuals with needing special assistance for disabilities or limited V1252 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.

Aggregate testing Back to Results Print. 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.

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. 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.

However, Test Method B provides additional information concerning the shape and texture characteristics of individual sizes. Typically, the material used to make wstm the standard graded sample can be obtained from the remaining size fractions after performing a single sieve analysis 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. A decrease in void content results is associated with more rounded, qstm, or smooth-surfaced fine aggregate, or a combination thereof. 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 void content is actually a function of the volume of each size fraction. This void content depends on grading as well as particle shape and texture. 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.

Request Quote Client Login. We have no document history for this standard. 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. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The fine aggregate is struck off and its mass is determined by c11252.

For more information, c125 Already Subscribed to this document. 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. Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void content determinations 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.
