4. Conclusions from the previous work In conclusion, for the first time, Cs 2 AgBiBr 6 double-perovskite ink was successfully synthesized through a route much simpler than existing methods at a temperature of 50°C. Although impurities were present, the presence of Cs 2 AgBiBr 6 double perovskite was confirmed by XRD. The bandgap of the ink material shows the presence of a semiconductor. While particle size analysis showed that the size of the ink particles is below 1000 nm.

5. II. I ntroduction What is Waste foundry sand ??? Waste foundry sand is generated as a by product of metal casting processes in foundries How much is it produced ?? Indian foundry industry is the third largest casting manufacturer in the world after China and USA. With approximately 5000 foundries and installed capacity of 15 Million metric tons/annum [ 1] Waste produced (WFS) from these foundries is approximately 1,710,000 tons (1.71 MT) per annum Applications: Waste foundry sand can be incorporated into composite materials, such as those made with epoxy resins, creating innovative and sustainable solutions for various industries [ 2] Figure 1 : Waste Foundry Sand (as received)

6. III. Literature Review Sand reclamation uses either physical, chemical or thermal treatment of foundry sands so that they can be safely re-used in place of new sand in molding and core making mixes[3] . Potential applications of WFS in Civil Engineering works can be – highway embankment filling [4] ; flowable fills; in road construction; in soil stabilization and reinforcement [5]; hydraulic barrier or liner [6] in cement manufacturing; mortar making [7]; pavement blocks, brick blocks [8]; asphalt concrete [9] Figure 2 : Different types of sand reclamation

Objectives To study anti-corrosion properties of mild steel coatd with WFS fines reinforced epoxy based PMC To study wear properties of of mild steel coatd with WFS fines reinforced epoxy based PMC To use WFS fines as a partial replacement for sand in concrete To utilize w aste foundry sand fines generated after sand reclamation process

8. V. Experimental work & Methodology
