PURPOSE: Provided are yellow earth bricks with improved durability, far-infrared emission, sterilization, and thermal conductivity compared with conventional yellow earth and cement bricks by using mica, yellow earth and white cement without binder. CONSTITUTION: The yellow earth bricks are manufactured by mixing raw materials, mica produced from Cheongyang, yellow earth, and white cement in a ratio of 3 : 6 : 1, for making a mortar; heating for 1-2hrs with a steam. The resultant yellow earth bricks have 0.93 of emissivity at room temperature and thermal conductivity more than 2-4times in comparison to conventional yellow earth bricks and cements.
