The Abrasion Test Study of Fly Ash Pavement Concrete in Cold Areas

Article Preview

Abstract:

Based on the freeze-thawing cycle characteristic of road concrete in cold climatic condition. The objective of this paper was to estimate the practicality of using fly ash discharged from a coal fuel electric plant in Inner Mongolia in concrete pavements. The abrasion resistance of road concrete containing fly ash was studied after suffering freeze-thawing cycles. The results indicate that the coarse aggregates were exposed after freeze-thawing cycle test and the replacement ratio of fly ash has little influence on the abrasion resistance.
