Loto, C.A., 1990. Effect of cassava flour and coal dust additions on the mechanical properties of a
synthetic moulding sand. Appl. Clay Sci., 5: 249-263.
An investigation has been made into the effects of cassava flour and coal dust additions on the
mechanical properties of a newly developed synthetic moulding sand made from lgbokoda clay and
\ silica sand. The results showed overall improved mechanical properties for both the cassava flour and
coal dust additions though with a slight tolerable decrease in toughness. The improved mechanical
properties, which resulted from the effective bonding property of cassava flour (starch) and fine
· bituminous coal particles, were obtained when a certain optimum level of each of the additives were
.! u sed with the optimum percent clay and tempering water.
