This study aims to investigate the development of sustainable construction materials (bricks or construction blocks) from brine sludge (a byproduct of chlor-alkali producing industry) and industrial waste materials (fly ash). Brine sludge is produced in substantial quantities and is typically disposed of in the industrial landfills. The major environmental problem associated with the industrial sector is linked to the disposal of brine sludge. The sludge contains toxic materials that precipitate from the brine. Over time, these substances can leach out, adversely affecting the ecosystem. The present study attempts to solve the problem of disposal of this industrial waste by developing sustainable construction materials from it. The primary objective is to develop an optimum mix proportion for manufacturing fly ash-cement-brine sludge (FCB) bricks. For this purpose, the concentration of brine sludge in mix proportion needs to be varied and its effect on the properties of FCB bricks need to be studied. The focus of this research is to determine the optimum mix proportion with fly ash-cement-brine sludge that yields FCB brick having high compressive strength and low water absorption. It has been targeted to create a viable alternative to conventional burnt clay bricks, particularly for superior construction work. The design mix will be prepared for the FCB bricks with specification of burnt clay brick strength and water absorption (as per IS 3495: 1992). Also, the X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), Scanning Electron Microscopy (SEM), and Toxicity Characteristic Leaching Procedure (TCLP) analysis on these samples are to be carried out to study their microstructural behaviour. Hence, the findings of the present study will support sustainable development in the area of waste management.
