Chloride Penetration Resistance Studies on Concretes Modified with Alkali Resistant Glass Fibers

摘要

Problem statement: This research study presented the durability performance of glass fibre reinforced concrete. Approach: The influence of fiber content on the durability performance of glass fibre reinforced concrete specimens having different percentage of glass fibres with varying grades of concrete were investigated. Results: The parameter of investigation included rapid chloride permeability test for aperiod of 365 days. Specimens of 100x150 mm cylinders were cast and tested to study their parameters. The specimens incorporated with addition of 0.03, 0.06 and 0.10% of glass fibres in M30, M40 and M50 grades of concrete. The durability performances of glass fibre reinforced concrete were compared with that of plain concrete. Conclusion/Recommendations: The results show that addition of glass fibres improves that durability performance appreciably.
