Study on the physico-mechanical properties of self-compacting mortar reinforced with glass fiber

Abstract

This study aims to evaluate the physico-mechanical properties of M50-grade self-compacting mortar reinforced with glass fibers in both fresh and hardened states. The experimental program was conducted with three fiber volume fractions (0,2 %, 0,3 %, and 0,4 %) and three fiber lengths (9 mm, 13 mm, and 17 mm). The experimental results showed that increasing both the fiber content and fiber length led to a reduction in the flowability of the mortar mixture, indicating a significant impact on the workability of the fresh mortar. In the hardened state, compressive strength was not significantly affected, whereas flexural strength and splitting tensile strength showed significant improvement with higher fiber volume and longer fiber lengths. These findings show the potential applicability of glass fiber-reinforced self-compacting mortar in civil and hydraulic structures, particularly for structural rehabilitation and repair solutions.
