Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or largesize gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soilcement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.

Some aggregates may be crushed to a powder while others may be screened to various diameter chunks. The proper processing of aggregates is important in maintaining their desirable qualities. For instance, between 60 and 75 percent of concrete consists of both coarse and fine aggregates. If the aggregates are not properly sized, as well as clean ...

sands. They are very stable and usually have ideal natural grading for concrete aggregates. China clay waste is the most widely used concrete aggregate in the region. This compendium has been assembled primarily as an aid to the identification of concrete aggregates used in the region, though section 2 provides a brief outline of degradation

Since the unit volume of Portland cement will also be reduced, concrete is less vulnerable to alkalisilica and sulfate attack. Processing blast furnace slag into slag cement or slag aggregate eases the burden on our environment in a number of ways. It reduces the air emissions at the blast furnace as well as the material in landfills.

For adequate consolidation of concrete, the desirable amount of air, water, cement, and fine aggregate (that is, the mortar fraction) should be about 50% to 65% by absolute volume (45% to 60% by mass).

Ore processing. Milling produces large chat waste piles and flat areas with tailings deposited in impoundments. Tailings generally contain higher concentrations of heavy metals and therefore present a higher risk to human health and the environment through direct contact. Chat typically ranges in diameter from 1/4 to 5/8 inch.
