The Environmental Impact of Recycled Concrete
2012-8-14 · Katz (2003) investigated the compressive strength of concrete which was crushed to serve as a source of aggregate for new concretes. In the investigation it can be noted that as smaller is the crushed aggregate as higher is the water absorption. Coarse aggregates among 9.54 to 25 mm had absorption of 3.3 in 28 days.
