The constant and unsustainable exploitation of naturally available aggregates have accelerated the depletion of their natural deposits at an alarming rate, due to which the present demands of the concrete industry are not fulfilled properly. By recycling waste products from various industries as aggregates or binder in concrete, the impact caused due to these products on the environment can be reduced to a great extent and a sustainable supply of aggregates for the concrete industry can also be preserved. In the present research work, the physical and mechanical characteristics of Refractory Brick waste aggregates (RBWA) obtained by crushing discarded refractory bricks into aggregates are studied to check the suitability of these materials as a possible alternative to natural coarse aggregates (NCA). Six concrete mixes were prepared with 0%, 20%, 40%, 60%, 80% and 100% RBWA by replacing the natural coarse aggregate to study the mechanical properties such as workability, density, compressive strength, split tensile strength, flexural strength of the concrete made with RBWA. A comparison was made with the conventionally made concrete. The test results indicate that though the RBWA are inferior to NCA, the workability of the RBWA concrete is good and the strength parameters are comparable to those of the conventional concrete. The attained strength did not show much difference for percentages about 20%, at which it reached the compressive strength of 32.36 N/mm2 in 28 days which was higher than the estimated target strength for the design mix. Hence, it is recommended for partial replacement of natural aggregates up to 20%.
