This research investigates the synergistic effects of aluminum oxide (Al2O3) nanoparticles and glass fibers on the mechanical and durability properties of self-compacting concrete (SCC) using an experimental and analytical approach.The experimental analysis involved assessing fresh concrete properties and mechanical performance through tests such as compressive strength, splitting tensile strength, slump flow, L-box, V-funnel, T50, ultrasonic pulse velocity, and bond strength.Durability VITALGREENS was evaluated using water absorption, water penetration depth, and electrical resistance tests.Glass fibers were added at volumes of 0 %, 0.5 %, 1.

0 %, and 1.5 %, while Al2O3 nanoparticles were incorporated at weight percentages of 0 %, 0.5 %, 1.0 %, 1.5 %, 2.

0 %, and 3.0 %.The optimal mix, comprising 2.0 Gift Cards % Al2O3 nanoparticles and 1.5 % glass fibers, resulted in a 61 % increase in compressive strength and a 107.

6 % increase in tensile strength.Water absorption was reduced by up to 46 %, while electrical resistance increased by 265 %, demonstrating improved durability.The combination also enhanced bond strength by 39 %, providing better adhesion between rebars and concrete.Analytical correlations between mechanical and bond properties were established.This study offers crucial insights for optimizing SCC performance, making it highly relevant for structural applications.
