The aggregate is then sorted or ‘screened’ according to the mesh sizes fitted, from large aperture mesh at the top, to small aperture mesh at the bottom. Screened stone is known as screenings or aggregate. In Australia, typical screened aggregate sizes are quarry dust, 7mm, 10mm, 14mm and 20mm.

Crushed Stone vs. Quarry Process vs. Stone Dust

Quarry Process. Quarry process, also known as QP, dense grade aggregate (DGA), crusher run and road stone, is a combination of small, 3/4-inch-or-less crushed stone and stone dust. Most often it is made out of crushed limestone, granite-gneiss, trap rock or a combination of the aforementioned.

aggregate physical properties, and, in particular, gradation (size control). Establishing a stable production process may reduce variability of the product. EXTRACTION With the exception of slag and other manufactured aggregates most materials for aggregate production come from bedrock or unconsolidated deposits.

Sep 10, 2015 Washing and classifying of aggregate can be considered in two parts, depending on the size range of material. Coarse material: Generally above 3/8 in. (sometimes split at 1/4 in. or #4 mesh). In the washing process it usually is desired to remove foreign, objectionable material, including fine particles. Fine aggregate: From 3/8 in. and smaller.

aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete’s freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed
