Investigation of the Fundamental Properties on the Color Concrete and the Development of Its Technique manufacturing Formative Article

컬러콘크리트의 기초적 물성검토 및 이를 활용한 조형물 제작기술 개발에 관한 연구

This study investigates the fundamental properties of the color concrete corresponding to the various types and contents of the coloring agent. For the properties of the fresh, the flow is gradually decreased corresponding to increasing of the coloring agent, and it is approached to the target flow on $3{\sim}6%$ of the adding amounts. The air content is increased in accordance with the increase of the coloring agent. For the properties of the hardened concrete, the compressive strength is increased about 9 and 12% in the case that $3{\sim}6%$ of red and yellow coloring agents is mixed. And they are decreased when white and black coloring agents. The chromaticity of red $(a^*)$ and yellow $(b^*)$ is appropriate at 6% of the adding amounts, and luminosity of the white and black is also favorable because of economy at 6%, so the formative article is manufactured successfully to aim in the result of this study.
