چکیده انگلیسی
The moulding properties of Igbokoda silica sand, bonded with Ijero-Ekiti clay, were investigated. American Foundrymen Society (AFS) standard cylindrical samples dimensioning Ã50 mm Ã 50 mm in height were prepared from various sand-clay ratios with 5% tempering water, by applying three ramming blows of 6.666 g each from a height of 50 mm as required for foundry sands. The samples were subjected to various physical and mechanical tests. These include permeability, green compression strength, and dry compression strength tests. Green shear strength, dry shear strength, field mould strength, shattered index and refractoriness tests were also carried out on the samples. Samples containing 23-32% clay were found to possess adequate permeability, good strength and refractoriness suitable for casting of both ferrous and non-ferrous alloys.
