Crushers break down large rocks into smaller pieces to such as sand, gravel, or slag to be used in aggregate via pressure or striking. Typically, rocks will go through multiple rounds of crushing to reach the desired size.
Particle size distribution curves of recycled aggregates from concrete pavement crushed by jaw and impact crushers. The jaw crusher produced 85% coarse aggregates (fraction >4.8 mm), whereas the impact crusher produced 82% coarse aggregates. In both cases, the content of particles finer than 0.15 mm was less than 2% mass.
Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
Strata Materials saves hundreds of thousands of tons of concrete and asphalt rubble from being disposed of in landfills annually by taking the material from demolition sites, crushing it, and sizing it into recycled construction materials.
Recycled Aggregate Characteristics. The crushing characteristics of hardened concrete are similar to those of natural rock and are not significantly affected by the grade or quality of the original concrete. Recycled concrete aggregates produced from all but the poorest quality original concrete can be expected to pass the same tests required ...

What is Crushed Concrete or Concrete Aggregate? Crushed concrete is made up of asphalt debris from other construction projects that can be reused to create driveways, pathways, garden beds and more. When any concrete structure, road, sidewalk or parking lot is demolished, that concrete is usually deposited in a landfill.
Recycling crushed concrete to be reused helps reduce landfill crowding AND saves more resources from being used to create new concrete. Old concrete can be crushed down to specific sizes, cleaned so that unwanted debris is removed from the mixture, and reused as a solution to a number of construction and landscaping problems.

Recycled Concrete is made up of asphalt debris from other construction projects & used as aggregate for fill, road base or new concrete. Thanks to increased environmental laws, and the desire to keep construction costs down, recycled concrete aggregate has quite a following. Recycled Concrete Aggregate (RCA) — also called "crushed concrete ...
Impact crushers are used to created crushed rock aggregate. The different aggregate sizes and types are appropriate for specific uses in the construction and landscaping industries. For example, although the larger, coarse crushed aggregates are more economical, this type of aggregate can present problems if used in concrete forms for upright structures.
In concrete aggregate processing line, the work of the portable concrete crusher for sale is crushing. The aggregate produced by crusher machine can be used to produce concrete, brick and so on; the mortar can be used to lay block and wallboard, etc; the stone screened by construction waste can be used to pave road and so on.
The crushed concrete aggregate has a faster initial set time than material, is lighter in weight, and simpler to place. When it has the right proportions, it has the same shrinkage properties as other concrete. Recycled concrete aggregate is more economical than using aggregates. The use of the circular economy is a great benefit ...
BRC is a locally owned and operated scrap metal yard which has served the greater Lynchburg area for over thirty years. BRC continues to buy and sell a wide range of scrap metals as well as recycled aggregates such as crushed asphalt and crushed concrete.
