Mechanical Properties and Color of Colored Concrete by Using Waste Earthenware Powder

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.

Advantage and Disadvantage of Colored Concrete in Structural Engineering

“…Curves from figure (3)to figure (9) show the relationship between colored mixtures age and strength the behavior of colored mixtures is very near to control mix. Comp.…”

“…Slump test result affected by addition of pigments in all colored mixtures, the highest colored slump was 85 mm and the lowest one was 75 mm in the ordinary Portland cement mixtures, the highest colored slump was 75 mm and the lowest one was 65 mm in the white Portland cement mixtures, table (8) shows the slump test results for every mix. Compressive strength results are shown in table (9),the results can represent the following points:…”

“…Furthermore, the color of concrete using the red earthenware powder was satisfied with the color evaluation of the wall of temples and shrines in traditional area of Kyoto. [9] There are three types of Colored pigments, and there is more than one way to perform colored concrete.…”
