Abstract

Fly-ashes are a potential alternative sand binder for production of foundry sand molds. They have previously been evaluated as binders for the main body of the mold, where they displayed suitable properties. Binders are also needed for producing foundry mold cores, which are separate shapes of sand that are placed in the mold to provide castings with contours, cavities, and passages that are not practical to produce with a simple mold. These cores have considerably higher strength requirements than the main mold and the ability of Class C fly-ash to meet the tensile strength requirements for cores was therefore evaluated.
