ABSTRACT: Old concrete in construction is a lot, and is receiving special attention from many studies. Through the study will show the mechanical behavior of samples of reinforced concrete materials containing material bolts from old concrete. The mechanical properties such as compressive strength, flexural strength and elastic modulus of the studied materials are compared with the mechanical behavior of natural aggregate concrete with compressive strength of 250 MPa. The results showed that the samples using old aggregates had increased mechanical properties and compressive strength.

KEYWORDS: old concrete, reinforced concrete, compression column.
