Abstract: This paper investigated the efficacy of moisture content and the bonding capacity of the River Niger Onitsha beach sand. Sieve analysis was conducted using electronic sieve shaker. Mechanical properties tested were green and dry compressive strengths, dry shear strength, permeability, refractoriness and fusion point using American Foundrymen Society Standard. The result obtained showed that green compressive strength was 21.69KN/m2, dry compressive strength was 210KN/m2, permeability was 150.50 No, refractoriness was 13880C, fusion point was 13900C and AFS grain fineness number was 81.81 for the moulded River Niger Onitsha beach sand. From the results, it was found that 3% moisture content and 4% of Ukpor clay were most suitable for moulding River Niger Onitsha beach sand for application in non-ferrous foundry and therefore, these results compared favourably with those obtained with bentonite. Ukpor clay could serve as a satisfactory alternative to bentonite for use as binding clay, in non-ferrous foundry.
