摘要
The abrasion resistance of concrete has been becoming more and more attention, this paper used ball bearing abrasion resistance test (GB/T16925-1997) to investigate the influence of mineral admixture on concrete abrasion resistance. Results indicates that concrete which is higher w/b (w/b = 0.5) can improve its abrasion resistance at 90d age when mixed with fly-ash, while mixed with both fly-ash and slag can improve its 28d and 90d abrasion resistance. Concrete which is lower w/b (w/b = 0.31), either mixed with fly-ash or with both fly-ash and slag, its abrasion resistance at 28d and 90d descends as well as the mixture content increased.
