Preliminary Study on Life Cycle Assessment of Concrete Containing Fly Ash

In this paper the impact of concrete containing different rate and percentage of fly ash on environment is described by using life cycle assessment method.The study shows that the mixing of fly ash can effectively reduce the consumption of coal and the discharge of CO_2,NO_X,SO_2 and the solid wastes,but can not reduce the discharge of CO and C_XH_Y,so the concrete containing fly ash can be thought as a good ecological material.
