Properties Of Concrete Using Crushed Brick As Aggregate

Date 2 1 1983. Abstract Four grades of concrete made with crushed brick as aggregate were tested to determine their physical and mechanical properties. Nominal compressive strength ranged from 2000 to 5000 psi (13.8 to 34.5 MPa). Test results compared favorably with those for normal weight concrete as obtained from the ACI code equations.
