Abstract

In the present work, attempt has been made to study the effect of variation in the percentage of additives on quality of moulds and hence the properties of aluminum castings. In this direction, three different additives namely, Fly-ash, Tamarind powder, and Coconut shell powder were used in different percentages. By using the best composition of moulding sand for each additive, sand moulds were prepared to cast Aluminum. On these Aluminum castings, hardness tests and surface roughness tests were conducted. The castings prepared using silica sand with 1% coconut shell powder, 7% of water, and 8% of bentonite have shown better Surface finish and hardness in comparison with tamarind powder and fly ash.
