Aggregate Angularity Apparatus

Introduction :Fine Aggregate Angularity Apparatus is used to determine the loose uncompacted void content of aggregate. This testing method provides an indication of aggregate spherical shape, angularity, and workability within a mixture. Test sample is mixed until homogeneous and poured into the funnel of the device while the funnel stem is blocked.

Shape tests of aggregate - SlideShare

Jul 27, 2018 The angularity number ranges from 0 for a highly rounded grave to about 11 for freshly crushed angular aggregates. Higher the angularity number, more angular and less workable is the concrete mix. In cement concrete roads (rigid pavements) rounded aggregates are preferred because of better workability and higher strength. In bituminous or water

Aggregates must meet certain specifications to be acceptable in asphalt and concrete applications. Among these are specifications that deal with the various aspects of aggregate shape, including flatness and elongation and aggregate angularity. The current practice for ensuring those specifications is the use of manual-mechanicaltests. These

a known grading, void content indicates theaggregate’s angularity, sphericity, and surface texture compared with other fine aggregates tested in the same grading. When void content is measured on an as-received fine aggregate grading, it can indicatethe effect of thefine aggregate on the workability of a mixture in which it isused. Apparatus

The Compacted Aggregate Resistance (CAR) test is a procedure used to analyze the quality of asphalt. It is a punch shear test that indirectly measures the shape and angularity of fine aggregates. The CAR test is in the developing process of replacing the current Superpave standard for fine aggregate angularity.

Mar 24, 2020 Thus, angularity number has considerable importance in the gradation requirements of various types of mixes such as bituminous concrete and soil-aggregate mixes. Thus, evaluation of shape of the particles, particularity with reference to flakiness, elongation and angularity is necessary.

Aggregate Washers are also available in two models. The automatic aggregate washers save time over the traditional manual method of washing clay and silt materials in preparation of particle size analysis. Fine Aggregate Angularity Apparatus determines the uncompacted void content (fine aggregate angularity) of fine aggregates.

Mar 24, 2020 The angularity of the aggregate can be estimated from the properties of voids in a sample of aggregate compacted in a specified manner. The angularity number ranges from 0 for a highly rounded gravel to about 11 for freshly crushed angular aggregates. Higher the angularity number, more angular and less workable is the concrete mix.
