Top 20 largest recycled aggregates producers list

29/04/2019 A recycling-friendly Texas Department of Transportation (TxDOT) has been another shot in the arm to secondary aggregates producers in that region. TxDOT says it “reclaims and reuses about 1 million tons of recycled concrete pavement (RCA)

The Environmental Impact of Recycled Concrete

The production of recycled aggregates in The United States is around 140 million metric tons per year, which correspond to 5% of total aggregate market (Taylor, 2007). The machinery normally used for natural aggregates transformation can not be used for recycled aggregates due to the metal content in the concrete; and metal must be sorted from aggregates (Wilburn y Goonan, 1998). Concretes

Recycled Aggregates Portland Cement Association

According to a 2004 FHWA study, 38 states recycle concrete as an aggregate base; 11 recycle it into new portland cement concrete. The states that do use recycled concrete aggregate (RCA) in new concrete report that concrete with RCA performs equal to concrete with natural aggregates.

Recycling Concrete for Sustainable Construction

Construction aggregates accounted for 70% by mass of all materials consumed in the United States in the late 20. th. Century (Mcintyre et al., 2009). Many scientists believe that concrete production alone produces 5 percent of humanity’s carbon footprint (NSF, 2009). In 1998, 3,400 U.S. quarries produced 1.5 billion tons of crushed

Effect of recycled concrete aggregates on strength and

RCA-PC1-I and RCA-PC1-M were produced from rejected hollow-core members at a precast concrete plant and were also sieved and recombined to form two different grada- tions. RCA-PC2-I and RCA-PC2-M were produced from re- jected hollow-core members at a second precast concrete plant and were again sieved into the two gradations.

THE SYNTHETIC AGGREGATE MARKET • Aggregate Research

Mineral aggregates are composed of sand, gravel, or crushed stone, which is quarried from glaciated areas, riverbeds, and alluvial fans. Over one billion tons of new construction aggregates annually comes from over 5000 U.S. quarries, and only 5% (100 M tons) is recycled concrete (Turley (IL) & USGS).
