Experimental Studies On Axial Compression Strength Of Geopolymer Concrete And Conventional Concrete Columns

Abstract

The High Carbon Emissions And Energy Consumption Associated With Ordinary Portland Cement (OPC) Have Prompted The Development Of Sustainable Alternatives In The Construction Sector. Geopolymer Concrete (GPC), Incorporating Industrial By-products Such As Fly Ash And Ground Granulated Blast Furnace Slag (GGBS), Presents An Eco-efficient Substitute For Conventional Concrete. This Study Investigates The Axial Compression Performance Of GPC Columns, With And Without Glass Fiber Reinforcement, In Comparison To M40-grade OPC Concrete Columns. Four Mix Series Were Designed: C-1 (M40), C-2 (M40 With Glass Fiber), C-3 (GPC With 10M), And C-4 (GPC With 10M And Glass Fiber), Each Measuring 1300 × 225 × 150 Mm. Among These, Mix C-4 Showed Superior Mechanical Properties, With A 4.39% And 8.07% Increase In Compressive And Flexural Strength, Respectively, Compared To C-1. Additionally, C-4 Achieved A 3.64% Higher Axial Compressive Strength Than C-1. Stress-strain Analysis Under Axial Loading Demonstrated Improved Ductility And Load-bearing Capacity Due To The Inclusion Of Glass Fibers. The Results Confirm That Fiber-reinforced GPC, Particularly With 10M, Is A Structurally Reliable And Environmentally Sustainable Alternative For Reinforced Concrete Columns.
