What are Concrete Aggregates?

In a concrete mix, aggregates usually refer to sand and gravel. Concrete is typically made from four base materials - cement, sand, gravel, and water. Cement is the binder that holds all of the ingredients together, sand and gravel are the aggregates that give concrete its bulk of yield, and water begins the chemical actuation of the cement binder.

Almost anything can be used as a concrete aggregate. There are all kinds of lightweight aggregates such as perlite, vermiculite, pumice stone, peat moss, and even soap bubbles. Shredded newspaper, ground coconut husks, tin foil, glass beads, broken glass, fiberglass, fly ash, blast furnace slag, ground wood ash. The list of possible concrete aggregates is virtually endless.

Concrete aggregates are anything that is added to the paste mixture of Portland cement and water. Aggregates are made from all kinds of different materials, some enhance the concrete strength, some will make the finished concrete weaker. Once the cement has hardened around the aggregates, the end result is concrete.

Is there any issue with recycling crushed concrete as more concrete aggregate?

concrete loses 1-0 at home but wins 1-3 away so on aggregate concrete wins

Thanks. What do you think of adding shredded plastics for sculpture / art purposes? In my past research, it seems I came across some people who are doing that?
