The demolition of concrete structures has made concrete debris the largest portion of the waste stream in the U.S. With landfills becoming scarcer, the need to recycle demolition debris is becoming increasingly relevant. An effective way to recycle this material is to produce recycled concrete aggregate (RCA) and use this material in
Waste & Recycled Material In Concrete Technology – 1000 Projects
Oct 02, 2011 · Waste & Recycled Material In Concrete Technology: Recycled-aggregate concrete containing fly ash is an example of construction material in harmony with this concept, whereby sustainable construction development is useful with satisfactory performance, in both safety and service of structures, at lower costs and with advantages over ordinary concrete.
The early phases of many construction projects involve the demolition of concrete foundations, sidewalks, driveways, and other concrete structures, which can leave a contractor with a sizable volume of heavy, dense materials to deal with. Fortunately, concrete can be recycled and reused in many ways. Typically (but not always) the process involves crushing or pulverizing the concrete rubble near the demolition or building site. Choosing the best method often depends on the size and shape of the
