PURPOSE: A manufacturing method of a loess brick which has a surface contamination control function is provided to prevent efflorescence of the loess brick by surface processing the loess brick with hydrogen water solution. CONSTITUTION: A manufacturing method of a loess brick which has a surface contamination control function comprises the following steps: manufacturing hydrogen solution by mixing 1.0-27.5 weight% of hydrogen ion and 72.5-99.0 weight% of water for 100 weight% of hydrogen solution; dipping a calcinated loess brick in the hydrogen solution for 15-30seconds in order to surface-process the loess brick; and natural drying the surface-processed loess brick. The hydrogen solution includes hydrogen fluoride and hydrochloride.
