Medium and high strength concrete made with high-volume and low-quality fly ash

Lin Feng-ting

Abstract

The application of low-quality fly ash to concrete is a efficient approach to reduce the pollution of waste metter.Based on the tests,the factors which affect the compressive strength oF low-quality fly ash concrete are investigated.The analysis result shows that the influence of water-binder ratio on the strength of low-quality fly ash concrete is the greatest,then the fly ash content,and then the binder composition.At the same time,the effects of fly ash quality on the strength of concrete are presented.
