Application of High Volume Fly-Ash Concrete in Mining Roads

The fly ash has become a major industrial solid waste of emissions in China. Lots of fly ash will not only take the land directly but also pollutes the atmospheric environment seriously. As a mineral admixture, fly ash concrete can not only improve technical performance of concrete, but also make full use of the industrial waste. Moreover, it is significant to reduce energy, resource consumption and environment contamination. Experiments show that the performance of high volume fly-ash concrete is good for the need of pavement engineering. It has important social significance to apply high volume fly-ash concrete in mining roads.
