Researchers demonstrate improved mechanical and bond characteristics in hybrid fiber-reinforced mortars, indicating strong potential for infrastructure repair.
Key Points
This research aims to explore the effects of hybrid fibers and ultra-fine slag on the performance of repair mortars.
Developed composite repair mortar with ultra-fine slag and hybrid fibers (ARGF and BF)
Conducted tests on fresh and physical properties, mechanical performance, and durability
Used SEM and XRD for microstructural analysis
Hybrid fiber mix (G50B50) improved compressive strength by 4.63% and flexural strength by 44.6%
Bond strength increased by 10.17% and energy absorption capacity by 49.83% over mono-fibrous mortar
Increased BF content reduced water absorption by 5.65% and capillary penetration by 41.43%
