Abstract

This paper investigates the possibility of recycling of demolished concrete blocks made with brick aggregates as coarse aggregate. For this, demolished concrete blocks from seventeen different demolished building sites were collected and crushed into coarse aggregates. As virgin aggregate, first class brick aggregates (normal brick aggregate) were investigated. About 200 concrete cylinders were made using normal and recycled brick aggregates with W/C=0.45 and 0.55. Test items include slump, unit weight, compressive strength, tensile strength, Young's modulus, and stress-strain curve. For the same W/C, recycled brick aggregate concrete shows lower compressive strength and Young's modulus compared to the normal brick aggregate concrete. The average strength of recycled brick aggregate concrete is found at 25.5 MPa (3700 psi) and 19.05 MPa (2762 psi) for W/C=0.45 and 0.55 respectively. The results indicate that recycled brick aggregates can be utilized for new construction works as normal brick aggregates.
