DEVELOPMENT OF PLANTABLE POROUS CONCRETE USING COAL ASH

Abstract

With the construction and expansion of coal-fired power plants, Japan's total amount of coal ash will sharply increase to approximately 10 million tons at the end of fiscal 2010. In this research, we developed a new type of plantable porous concrete that incorporates the coal ash (clinker ash and fly ash) that is created a by-product of coal-fired power plant operation. The characteristics of coal ash make it suitable for use in plantable porous concrete, and we were moreover able to develop a mixture that ensures a high coal-ash utilization factor.
