Abstract
This study was aimed at investigating the effect of moisture content of Nasarawu natural foundry sand. The moisture content was varied from 2 to 10% to determine its effect on green compressive strength, dry compressive strength, green shear strength, shatter index and green permeability. The particle size distribution, the grain fineness number and the clay content of the natural sand were also determined. The results indicated that the dry compression strength increased with moisture content, and an optimum value 99.7 psi was obtained at 10% moisture content. At the same time, 6% of moisture content gave the optimum green compressive strength of 118.6KN/m2 . Nasarawu natural sand had an average grain size of 138.73microns, clay content of 25.2% and refractoriness value of 14000C. A sand mixture containing 6% moisture was prepared and used to produce a test casting with aluminium scraps, and the cast was sound. This shows that Nasarawu natural moulding sand is suitable for a wide range of non-ferrous metal casting.
