The purpose of this study is the development of structural material with its superior strength and fire-resistance in
historical city landscape. It is thought that reusing of waste colorful earthenware powder as admixture material of
concrete is effective to color the concrete. In this study, the physical properties and the color evaluation of concrete
using the earthenware powder were examined. As a result, the strength and coloring effect of concrete increased with
the increase of the replacement ratio of the earthenware powder. The color of concrete using the earthenware powder
was satisfied with the color evaluation of the walls of temples and shrines in traditional area of Kyoto.
Key Words : earthenware powder, colored concrete, strength, color evaluation
