Abstract:The purpose of this study is the development of structural material with its superior strength and durability 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 mechanical properties and the color evaluation of colored concrete by 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. Furthermore, the color of concrete using the red earthenware powder was satisfied with the color evaluation of the walls of temples and shrines in traditional area of Kyoto. Key Words:Waste earthenware powder, Colored concrete, Strength, Color evaluation, Weatherability
