Abstract The study was conducted to investigate the feasibility of sodium aluminate activation nonferrous waste foundry sand. aim solidify sand via geopolymerisation into useful civil engineering materials. Green mixed with make a paste which filled 50 × mm 3 mold. mixture cured in an oven for 5 days. concentration aluminate, granulated blast furnace slag (GBFS) : (WFS) ratio, liquid solid rati...

As part of the casting process, foundries create sand molds and cores to hold the molten metal to specific dimensional tolerances. Although most of the waste foundry sands (WFSs) from this process are land filled, there is great interest in diverting them for use in agricultural and geotechnical applications. One potential limitation to their beneficial use is concern that the WFSs will leach h...

In this work, leftover foundry sand and vermiculite were used as partial replacements for fine coarse aggregates in hybrid fibre reinforced concrete (HFRC). The study also concentrated on HFRC mix percentage optimization to achieve desired attributes. By creating multiple mixtures with varied ratios of vermiculite. mechanical characteristics the assessed. Tests HFRC’s permeability, water absorp...

Abstract Due to significant industrialization, many countries have adopted the practice of industrial symbiosis, which involves utilizing waste produced by one industry as a resource for another industry. The utilization spent foundry sand (SFS), is derived from metal casting industry, poses risk both environment and living organisms result existence inorganic organic substances. Nevertheless, ...
