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. In general, for the same grade of concrete the modulus of elasticity is about 30 percent lower and tensile strength is about 11 percent higher than normal weight concrete. Empirical equations predicting modulus of elasticity and tensile strength of brick aggregate concrete have been derived. Brick aggregate can be used to produce high-grade quality concrete. The unit weight is about 125 to 130 lb per ft3 (2000 to 2080 kg/m3). As the properties of brick aggregate concrete lie between those of normal weight and lightweight concrete, it may be classified as medium weight concrete.


Keywords: aggregates; compressive strength; crushed brick; flexural strength; mix proportioning; modulus of elasticity; splitting tensile strength; tensile strength.
