ABSTRACT:
A red brick comprising waste foundry sand of 30.about.50 wt %, dusts of 5.about.10 wt %, and a remainder of clay. The waste foundry sand and dusts can be efficiently recycled, and the quantity of the sand used, the supply of which sand which is nearly exhausted, can be reduced. The heating temperature in the red brick manufacturing process is remarkably lowered, and the economical efficiency of the manufacturing process is improved greatly by using iron oxide included in dusts, instead of a chemical compound to obtain desired color.
