Experimental Study and Life Cycle Assessment of High Volume Fly Ash Concrete

Abstract:

One of the effective ways of low carbon concrete is to reduce the cement content. It can not only reduce the greenhouse gas emission, but also improve the comprehensive utilization of industrial solid waste. In this paper, the mix design and experimental research of C15 Self-Compacting Concrete (SCC) were carried out by substituting cement with high volume fly ash. A partition coefficient of environmental burden Cm was introduced in order to assess the environmental effect of different mix proportion SCC precisely by using life cycle assessment method. Evaluation results showed that the mixing of fly ash can reduce the consumption of coal, the discharge of CO2 and the solid wastes effectively. The study provided a rational basis for the high performance and low cost fly ash concrete.
