dc.descriptionLoto, C.A. and Adebayo, H., 1990. Effects of variation in water content, clay fraction and sodium carbonate additions on the synthetic moulding properties of Igbokoda clay and silica sand. Appl. Clay Sci., 5: 165-181. In this investigation, the Igbokoda pure silica sand is characterised and used as a base sand for the Igbokoda clay- sand mixture in an attempt to develop an efficient synthetic moulding sand. The mechanical properties of the clay-sand-water mixture were determined. The effect of additions ofNa2C03 to the moulding sand was examined with particular attention to its influence on mechanical properties of the synthetic moulding sand. The fineness number, screen bulk fraction, total coarse fraction and the total fine fraction of Igbokoda silica sand were found to be within the range that could give good mouldable properties. The values obtained for the green compressive strength, the dry compressive strength, the green and dry shear strengths, collapsibility and toughness indicate that Igbokoda clay has good values as a binder for synthetic moulding sand. In general, the addition of Na2C03 gives improved properties to the moulding sand though with a tendency towards impaired collapsibility values.
