Permeability of High-Performance Fiber Reinforced Concrete Immersed in High Concentration Sodium Chloride Solution

This paper aims to study the permeability of High-Performance Concrete containing natural pozzolan and reinforced with fibers in high concentration sodium chloride solution. Optimized finely ground was employed as 6% partial substitution cement. Polypropylene 6 mm 12 lengths were introduced individually for a volume fraction 0.1% 0.15% respectively. Then, combination total fiber content 0.25%. The effect attack on performance concretes assessed through measurement compressive strength, splitting tensile sorptivity, rapid test, apparent intrinsic gas permeability, visual inspection at various testing ages (28, 90, 180, 365 days). A four (04) types cast: one (01) (HPC), three (03) Fiber Reinforced (HPFRC) stored tap water environment. From experiments performed, it can be concluded that polypropylene introduction into HPC favorably affect its chemical resistance long-term durability. difference HPFRC environment is not significant. Furthermore, investigation after days immersion showed no sign degradation. Based results obtained this study, we recommend use hybrid fiber-reinforced concrete (F0-0.25%) low permeable material severe
