| Abstract: | In this paper,the high-performance concrete for chamber wall of navigation lock was prepared by three-mixture technology including grade I fly ash,PVA fiber and poly-carboxylic acid super-plasticizer.The effects of cement types,fly ash content,and organic fiber on impacting and abrasion resistance of the high-performance concrete were studied.The results showed that PVA fiber could obviously improve the impacting and abrasion resistance and impact resistance of the concrete.The impacting and abrasion test method of concrete for navigation lock was feasible for testing and evaluating the impacting and abrasion resistance of concrete. |
