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

Abstract: 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 a period of 365 days. Specimens of 100×150 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.
