Abstract:

The suitability of crushed clay bricks as coarse aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete. Four basic mixes were chosen for crushed granite to achieve concrete with grades from 30 MPa to 60 MPa. The equivalent brick-aggregate concrete for each mix was obtained by replacing granite with an equal volume of crushed bricks, everything else remained the same. Test results indicate that brick-aggregate concrete can attain the same compressive strength, gives a higher tensile strength, a lower drying shrinkage, and almost identical specific creep when compared with conventional concrete. However, it exhibits a substantially smaller elastic modulus. Also, the peak stress is reached at a much higher strain. An equation is presented to generate the complete stress-strain curve of brick and granite-aggregate concretes with a good degree of accuracy.
