Abstract

This study investigates the properties and performance of alkali-resistant glass fiber reinforced concrete (ARGFRC) through a series of experimental tests. As concrete structures are increasingly exposed to aggressive environments, the incorporation of alkali-resistant glass fibers presents a promising solution to enhance durability and mechanical strength. The research focuses on the effects of varying fiber content and fiber lengths on key properties such as compressive strength, flexural strength, workability, and resistance to alkali-induced degradation.

Concrete samples were prepared with different proportions of alkali-resistant glass fibers and subjected to a range of tests to evaluate their performance under standard conditions. The findings indicate that the incorporation of AR glass fibers significantly improves the mechanical properties of concrete, enhancing both its compressive and flexural strength compared to conventional concrete mixtures. Additionally, the study demonstrates that AR glass fibers effectively mitigate the effects of alkali-silica reaction (ASR), contributing to the long-term durability of concrete structures.

The results of this investigation provide valuable insights into the optimal fiber content and distribution for achieving desired performance characteristics in ARGFRC. This research underscores the potential of alkali-resistant glass fibers as a reinforcement material in concrete applications, promoting more durable and resilient infrastructure. The findings contribute to the ongoing efforts to improve concrete performance in challenging environments and suggest avenues for future research in advanced concrete composites.
