Abstract:
This Study Investigates The Performance Of M25 Grade Geopolymer Concrete (GPC) Slabs Reinforced With Glass Fibres (GF). Four Slab Specimens Of Size 600 Mm× 600 Mm × 50 Mm Were Casted And Tested Under Static Loading. The Mix Variations Included: (S1) Conventional M25 Concrete, (S2) M25 + GF, (S3) GPC M25 With 8 Molarity (8M) And (S4) GPC M25 + GF - 8M. Mechanical Properties Such As Compressive Strength, Flexural Strength, And Flexural Behaviour Were Evaluated. Among All Specimens, The Hybrid Fibre-reinforced GPC Slab (S4) Demonstrated The Best Performance. It Showed The Highest First Crack Load, Ultimate Deflection, And Enhanced Post- Peak Behaviour Under Flexural Loading. The Static Test Results For Specimen S4 Revealed An Ultimate Load-carrying Capacity Of 26.61 KN, A Ductility Index Of 8.72, And A Toughness Index Of 30.54. These Results Indicate That The Integration Of Glass Fibres Significantly Improves The Load- Bearing Capacity And Ductility Of GPC Slabs, Making Them A Viable Alternative To Conventional Concrete In Structural Applications
