Refractory bricks are used as lining material in furnaces, kiln and are discarded as a waste material after a few cyclic uses. Most of the waste refractories are dumped in the ground, managing and disposal of these wastes is one of the most challenging global issues today, dueto lack of storage land. Hence the authors have taken a keen interest to utilize it in the construction sector to a greater extent. Although there are a few literatures available on the topic of interest, particularly mechanical behavior, much is yet to perform in the application regime. This article has attempted to utilize Recycled Refractory Brick Fine Aggregate(RRBFA) in a number of RC Sustainable Beam with a view to check its shear performance. The authors have cast four M25 grade beams 1100 × 100 × 150 mm (L × B × H), two normal control beams and two with RRBFA as alternative to natural FA, and carried out test in a 1000 kN computerised servo controlled four-point loading frame. Strain and deflections have been measured by using strain gauges and LVDTs. Experimental results revealed that control beam has the initial crack load of 22 kN, reaching an ultimate load of 96.3 kN at a central deflection of 7.33 mm. In contrast, RRBFA integrated sustainable beams displayed an initial crack load of 26.1 kN, reaching an ultimate load of 92.6 kN at a central deflection of 7.35 mm. The experimental outcomes indicated that the RRBFA incorporated sustainable beam exhibited a comparable failure pattern, peak load and deflection to that of control beam.
