Using compressive strength and chloride ion permeability as the main indicators,the influence of different amounts of active mineral admixtures such as silica fume,fly ash,and slag powder on the marine application of reactive powder concrete(RPC)was studied.The research results indicate that single addition of silica fume,composite addition of silica fume and fly ash,composite addition of silica fume and slag powder have a good effect on the compressive strength and chloride ion permeability of high content mineral fine powder RPC.Replacing some cement and silica fume with fly ash can not only achieve good durability,but also reduce compressive strength loss,and further reduce engineering application costs,which has certain engineering reference significance.
