Abstract
PURPOSE: To increase the adsorption amount of methylene blue and enable the obtaining of high green strength with addition of a small amount to aggregate by adding respectively the specified amounts of MgO and Mg(OH)2 or MgCO3 to the bentonite for molding sand.
CONSTITUTION: MgO is added at 0.5W20wt% or Mg(OH)2 at 0.7W30wt% or MgCO3 at 1W40wt% to bentonite for molding sand. The green sand mold molding sand 1.2.3. comprising adding the resultant bentonite to silica sand together with water has higher compressive strength irrespective to whether the moisture content is high or low as compared to the green sand mold molding sand 0 using the bentonite not added with the above-mentioned Mg compound.
