Flexural Behaviour Of Glass Fibre Reinforced Geopolymer Concrete Beam

Abstract

The Present Research Investigation Deals With The Study Of Test Beam Specimens Of M40 Grade Of Concrete Integrated With Glass Fibers (GF) Under Static Loading. A Series Of Four Test Beam Specimens Of 1500 X 250 X 150 Mm Dimensions Were Considered. The Study On The Flexural Behavior Of Geopolymer Concrete Beams Explores Into The Innovative Use Of Alternative Materials In Construction To Enhance Structural Performance And Sustainability. Through A Series Of Experiments, Various Concrete Mixes Were Tested, Including (B-1): Controlled Specimen CC M40, (B-2):CC M40+GF,(B-3):GPC M40-10M, (B-4):GPC M40+GF To Evaluate Their Compressive Strength, Flexural Strength, And Load-bearing Capacities Under Static Loading Conditions. The Experimental Investigation Deals With The Static Loading Which Was Carried Out Under Two Point Loading At Mid-point With The Help Of Load Cells Attached Vertically To A Hydraulic Jack And LVDTs Placed At Center. Various Parameters Such As Ductility Index, Toughness Index, Ultimate Deflection, Yield Deflection And Energy Absorption Capacity Are Studied. The Static Tests Performed On The Beams Shows That The Ultimate Load Carrying Capacity, Ductility Index And Toughness Index Of (B-4):GPC M40-10M+GF Of Beam 150x250x1500 Mm Is 98.36 KN, 7.07 And 25.065 Respectively.
