Abrasion Resistance of Concrete Pavements with Fly Ash from China After Freezing and Thawing Action

Abstract

Based on the climate characteristics and concrete pavements in Inner Mongolia of China the objective of this study is to estimate the practicality of using fly ash in concrete pavements which is discharged from coal fire power stations in Inner Mongolia Abrasion depth was measured after freezing and thawing test and it was indicated that the abrasion was not influenced by fly ash replacement ratio in concrete because of the better abrasion resistance of the surface coarse aggregates after freezing-thawing test. Chinese fly ash is available for general use up to 50% replacement on standard concrete pavement in China.
