Abstract: 

An investigation into the suitability of Lere river bank sand for use in green sand casting process was conducted. The samples of sand were tested for Refractoriness, Sieve analysis, Clay content, Moisture content, Shatter index, Dry and Green strength as well as Chemical analysis. The sand was divided into four specimens and tested with different percentages of bentonite clay as a binder which responded well. The result of the mechanical properties analysis was compared to existing foundry standard and it was found to be very suitable for all types of non ferrous alloy casting. The result showed that Lere river bank sand is alumina silicate with physio-chemical properties that are suitable for non-ferrous alloy casting because of its low refractoriness.

Keywords: 

green sand, silica sand, bentonite, non-ferrous alloys, sieve analysis.
