The effectiveness of these test methods of determining void content cc1252 its relationship to particle shape and texture depends on the relative density specific gravity of the various size fractions being equal, or nearly so.

An increase in void content by these procedures indicates greater angularity, less sphericity, rougher surface texture, or combinations thereof. When void content is measured on an as-received fine-aggregate grading, it can be an indicator of the effect of the fine aggregate ast the workability of a mixture in which it may be used.

Uncompacted void content is calculated using the bulk dry specific gravity of the fine aggregate. 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.

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. A decrease in void content results is associated with more rounded, spherical, or smooth-surfaced fine aggregate, or a combination thereof. 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.

A sample axtm of single-size particles will have a higher void content than a c12552 sample. As the voice of the U.

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. Aggregate testing Axtm to Results Print.

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.

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 from tests of each of the three individual size fractions. In general, high aastm 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.

Two use graded fine aggregate standard grading or as-received gradingand the other uses several individual size fractions for void asym determinations: Aggregate testing Lab Services: 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. Two use graded fine aggregate standard grading or as-received gradingand c12252 other uses several individual size fractions for void content determinations 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.

If the document is revised or amended, you will be notified by email. If the type of rock or minerals, or its porosity, in any of the size asmt varies markedly it may be necessary to determine the specific gravity of the asmt fractions used in the test. The fine aggregate is struck off and its mass is determined by weighing.
