Abstract: Anti-erosion property, transparent property and microstructure of optical fiber light conductive concrete (OFLCC) were investigated by means of sulfate attack resistance and alkali solution corrosion resistance tests, ultraviolet visible near infrared spectrophotometer, XRD and ESEM. The results show flexural and compressive strength of OFLCC are increased with the decrease of optical fiber spacing, and the strength of OFLCC after alkali solution corrosion is generally lower than after sulfate attack. Light transmittance of OFLCC is increased with the decrease of optical fiber spacing, and light transmittance measured value is less than theoretical value. After curing in alkali solution, light transmittance of OFLCC is higher than after curing in sulfate solution, and light transmittance of them is higher than before curing. Hydration products of OFLCC have a rich C-S-H gel, hydroxyl calcium stone ettringite and gypsum, and interwoven in the hydration products more compact, but alkali solution corrosion to OFLCC is more serious than sulfate attack.
