The effects of alikama cereal and clay binder additions and moisture contents on the functional properties of clay-bonded core and moulding sands are explored. The outcomes suggest that improved functional properties resulting from the effective bonding properties of the cereal and clay binders were obtained when a certain optimum level of each of the additives was used with the optimum percentage of cereal binder and tempering water. This work establishes the viability of the cereal binder addition in a clay bonded core and moulding sand mixes for industrial and laboratory applications.


Die uitwerking van byvoegings van graan- en kleibinders en voginhoud by gietvormklei vir gebruik by gietprosesse word ondersoek. Die resultate dui op verbeterde funksionele eienskappe wat voortspruit uit optimum benutting van bestanddele.
