The present invention relates to a yellow soil hardener for producing building materials such as an environment-friendly brick and a board by using a yellow soil material, and particularly, to a hardener for molding yellow soil to produce a molded article without generating cracks, having good strength and attaining rapid binding with mortar. The yellow soil hardener of the present invention is obtained by mixing 15-35 parts by weight of calcium chloride (CaCl2·2H2O), 0.3-1.0 parts by weight of magnesium chloride (MgCl2·6H2O), 20-40 parts by weight of ammonium chloride (NH4Cl) and 20-30 parts by weight of sodium hydrogen carbonate (NaHCO3) based on 2,000 parts by weight of water. |
