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.

Grading of Aggregates Aggregate Grading The

Grading of Aggregates. Grading of Aggregates is one which is made up of stones of different sizes, ranging from large to small (inclusive of sand) so as to have minimum of air voids (and that will have maximum density) when mixed together.In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate.

A Detailed Guide on Grading of Aggregates.

Grading of aggregates is aimed at determining the mean size of the particle in a given batch of aggregates. This is commonly found by the Method of Fineness Modulus. The method can be used to determine fineness modulus of coarse aggregates, fine aggregates, and all-in aggregates, i.e., mixed aggregates.

Crushed Stone Grades: A Complete Guide

By definition crushed stone is a construction aggregate. It is created by mining a suitable rock formation and then using a crusher to break down the stone into different sizes. Crushed stone differs from gravel in that gravel has a more rounded shape and is made by the natural processes of weathering and erosion.
