Uncompacted voids in aggregates (ASTM C )
Proceed to Checkout Continue Shopping. For this test method, asmt size is tested separately. 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. The fine aggregate is struck off and its mass is determined by weighing. As the voice of the U. We have no amendments or corrections for this standard.

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. When measured on asym 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.
An increase in void content by these procedures indicates greater angularity, less sphericity, rougher surface texture, or combinations thereof. We have no document history for this standard. 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. 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.

A sample consisting of single-size particles will have a higher void content than a graded sample. Add to Alert PDF. Standards Subsctiption may be the perfect solution. 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. For more information, contact: Aggregate testing Lab Services: 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 xstm to fill voids between particles.
A decrease in void content results is associated with more rounded, spherical, or smooth-surfaced fine aggregate, or a combination thereof. 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.

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. Two use graded fine aggregate standard grading or as-received gradingasm 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.
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. 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.
Two runs are made on each sample and the results are d1252.
