【Abstract】 ∵ Inorder to explore the influence of basalt fiber on the performance and chloride ion penetration resistance of marine concrete and its mechanism，the basalt fiber withlengthof12 mm，18 mm and24 mm was mixed into marine concrete with 0.1% ，0.15 % ， 0.2% ， 0.25% and 0.3 % volume content respectively by volume mixing method，the mechanism of diferent fiber variables in concrete was analyzed by the corresponding characterization characteristics of working performance，and the influence of corresponding fiber variables on the electricflux of concrete was studied.Theresults showed thatthe fiber content is the main factor affecting the performanceand chloride ion resistance ofconcrete，and the fiber length was the secondary factor affecting thechloride ionpenetrationresistanceofconcrete.With the increaseoffiberlength，the electric fluxof concrete shows a downward trend asa whole，and the chloride ionresistance ofconcrete was proportional to the fiber length.

【Key words】：basalt fiber;marine concrete;chloride ion penetration resistance

氯離子侵蝕是導(dǎo)致鋼筋銹蝕并引起海工混凝土結(jié)構(gòu)破壞的主要原因，而鋼筋銹蝕速度與混凝土的滲透通道有著明顯的對(duì)應(yīng)關(guān)系；因此，海工類腐蝕環(huán)境下的混凝土結(jié)構(gòu)須采用抗?jié)B性良好的建筑材料。（剩余7893字）
