ABSTRACT:
There are provided a dry aggregate mixture wherein the binder, even when heated, does not evolve unpleasant odor or gas hazardous to human health; a method of foundry molding wherein a space for foundry molding, up to minute portion thereof, can satisfactorily be filled with an aggregate mixture composed of a binder and granular aggregate; and a method of foundry molding wherein the mold used in molding of an aggregate mixture composed of a binder and granular aggregate can retain satisfactory properties even in high humidity. In the method of foundry molding, a mold is formed by the use of a dry mixture obtained by providing an aggregate mixture composed of granular aggregate, a water soluble binder and water and evaporating the water contained in the aggregate mixture through heating, pressure reduction or aeration while mixing so as to effect separation into single granules, or with the addition of a lubricant and a crosslinking agent thereto.
