SENSIBILITY EVALUATION TO COLORED ARCHITECTURAL CONCRETE USING COLOR SAND AND PIGMENTS

Abstract

Architectural concrete in Japan has been valuated from the viewpoint on design in the foreign countries, because the texture of the concrete using painting form is smooth liking a mirror and lucid, and the image is stern. However in the present circumstances, there were extremely few reports on quantitative analysis of the influence of the surface properties on the image of colored architectural concrete. In this study ,as a basic examination, the concrete test pieces was made by using color sand and pigments. The influence on the gloss and the color of concrete was experimentally examined using materials and forms. And using those test pieces, the image tests were carried out. The influence on the image of colored architectural concrete was experimentally examined using the surface properties of concrete. According to the result, the correlation between the surface properties of colored architectural concrete and the materials was clarified, the images of colored architectural concrete were extracted, and the relation between the surface properties and the image was quantified.
