摘要

PURPOSE: Provided is a method for manufacturing yellow earth bricks with high strength, no cracks and far infrared emission by mixing yellow earth with inorganic admixture instead of cement. CONSTITUTION: The admixture used in manufacturing yellow earth bricks comprises 60wt.% of blast furnace slag, 10wt.% of anhydrous gypsum, 20wt.% of F2 gypsum and 10wt.% of slaked lime. The yellow earth bricks are manufactured by mixing(3) 85wt.% of yellow earth with 15wt.% of admixture, kneading(4), forming(5), and drying(6) under the sun.
