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. Medium aggregates (2.36 to

Concrete, cement and other wastes in construction waste can be used as building aggregates and recycled brick raw materials after being reasonably crushed, screened and crushed. And the main equipment used for crushing concrete can be divided into two types: traditional fixed crusher and mobile concrete crusher, among which small crushing equipment is favored by users.

From examined waste (crushed concrete waste) our tested concrete samples with dimension 150 mm were prepared. In these samples, fractions 4/8 mm and 8/16 mm by recycled concrete aggregate with a range of variation from 0 to 100% were replaced. Experiment samples were tested for compressive strength after 2, 7, 14 and 28 days of hardening. From obtained results it is evident that all samples
