Life Cycle Assessment of Aggregates
the Life Cycle impacts of excess production of fines, washing of recycled aggregates to enable further processing of fines and other aggregate sizes and the disposal options for inert construction and demolition wastes. The model includes impacts related to transport of primary and recycled aggregates from source to the market place, introducing a spatial dimension to the LCA process within

Aggregate Processing and Aggregate Crushing Plant
Aggregate crushing plants are important equipment for aggregate processing. Aggregate commonly is classified into two categories: fine aggregate and coarse aggregate. Fine aggregate is the materials that could pass the No.4 sieve, and most could be retained on a No. 200 sieve. Coarse aggregate is a relatively big materials that will get through a 3-inch screen and be retained on the No.4

What is Crushed Aggregate? (with pictures)
This process might be handled in a screen shaker or during the washing process in an aggregate washer. If the aggregate is sufficiently crushed, it is transported to the storage area. If the stone is not crushed to the desired size and type, the process is repeated or the stone is transported to other equipment for further processing.

3. The Environmental Impacts of Aggregate Extraction
Aggregate is mined from the earth, either dug out of pits or blasted out of quarries. This process has many significant environmental impacts. Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath. Not only does this lead to a loss of existing animal wildlife, it also leads to a huge loss of biodiversity

Construction Aggregates 101: What They Are (and Why
Aggregates are only as good as their processing. They are mined, crushed, washed, and separated. The successful outcome of each step, the processing of a good aggregate, depends on the success of the previous step. That success depends on the hardworking men and women in the aggregates industry, men and women who often go overlooked and underappreciated in the construction industry.
