Performance Evaluation Of M30 Self-compacting Concrete Utilizing Magnetically Conditioned Water And Sustainable Mineral Replacements

Abstract

This Experimental Study Investigates The Fresh And Hardened Properties Of M30-grade Self-compacting Concrete (SCC) Prepared Using Magnetic Field-treated Water (MFTW) At A Field Intensity Of 0.8 Tesla. To Enhance The Sustainability And Economic Feasibility Of The Mix, Ordinary Portland Cement (OPC 53 Grade) Was Partially Replaced With Silica Fume At Intervals Of 0%, 10%, 20%, 30%, 40%, And 50%. Simultaneously, The Fine Aggregate Component Was Partially Replaced With Industrial Waste By-products, Utilizing Sintered Fly Ash Aggregate (0%–50%) And Foundry Sand (0%–25%). The Fresh-state Characteristics Of The Concrete—specifically Filling Ability, Passing Ability, And Segregation Resistance—were Systematically Evaluated Using Standard Slump Flow, J-ring, L-box, And U-box Testing Methods. To Determine The Mechanical Behavior Of The Modified Concrete Matrix In Its Hardened State, Destructive Testing Was Conducted To Evaluate Compressive And Split Tensile Strength. All Specimens Were Subjected To Standard Wet Curing And Tested At Intervals Of 7, 14, And 28 Days. The Primary Objective Of This Research Is To Establish A Comprehensive Comparative Analysis Between The Performance Profiles Of These Multi-component, Magnetically Conditioned Concrete Mixes And Conventional Self-compacting Concrete Configurations.
