Recent advances in artificial aggregate production

Granulation is a process of consolidating solid particles in the size range of 1–500 μm into aggregates with larger sizes ranging from 2 mm to 10 mm ( Ennis and Litster, 1997 ). Presently, the commonly applied granulation methods in producing AAs can be divided into agitation granulation and compaction granulation.

Sampling of Aggregates

Remove approximately 6 inches (15 cm) of surface material. Use a flat, square end shovel or scoop with sides for sampling. In sampling stockpiles of fine aggregate (3/8 in. (minus 9.5 mm)), the outer layer, which may have become segregated, should be removed and the sample taken from the material beneath.

TIP 3

At a ready mixed concrete plant aggregates are typically stored in a bin or a stockpile. The process of taking a sample of aggregate that is truly representative of the nature and condition of the aggregate in the stockpile, bin or transfer point is called aggregate sampling. ASTM D75 is the standard practice for sampling aggregates.

Theoretical Models, Preparation, Characterization and …

Molecule size is also an important factor in their aggregation. On the one hand, large molecules convert to J‐aggregate more easily, but on the other hand, a short methine chain makes it easier to obtain a J‐aggregate. Thus, more work is needed to better understand the parameters that promote or inhibit aggregation.
