Abstract

PURPOSE: To produce sand mold free from offensive smell and occurrence of alkali pollution by discarded sand and having sufficient strength, by adding dicarboxylic acid and water into sand for casting, and adding oxide or hydroxide of bivalent or trivalent metal.
CONSTITUTION: Casting sand is mixed with, in the presence of a slight quantity of water, dicarboxylic acid, especially preferably aromatic dicarboxylic acid such as unsaturated dicarboxylic acid like malonic acid and succinic acid, and oxide or hydroxide of bivalent or trivalent metal, especially preferably oxide or hydroxide of magnesium or aluminum. The casting sand used in this invention has the merit that the sand once may be used repeatedly. During repetition of use, it is not necessary to add magnesium oxide. The ratio of dicarboxilic acid A to casting sand D, which is A/D by weight, should be 0.005 or more.
