Abstract:
This Study Examines The Combined Influence Of Fly Ash (FA), Vitrified Polish Waste (VPW), And Ground Granulated Blast Furnace Slag (GGBFS) As Supplementary Cementitious Materials (SCMs) In M40 Grade Pavement Quality Concrete (PQC). Cement Was Partially Replaced In Incremental Proportions Of 5%, 10%, 15%, And 20% Using Blended Combinations Of FA And GGBFS Along With A Fixed 15% VPW Content. All Mixes Were Designed With A Constant Water-to-binder Ratio Of 0.34 Following IRC:44-2017 Guidelines. Mechanical Performance Was Evaluated Through Compressive Strength, Split Tensile Strength, And Flexural Strength At 7 And 28 Days. Results Indicate That Mechanical Strength Steadily Increased With SCM Content Up To An Optimum Replacement Of 15%, Beyond Which Performance Declined. The Optimum Mix Exhibited Superior Compressive, Tensile, And Flexural Behavior Compared To Conventional M40 PQC. This Study Demonstrates That Incorporating Industrial Waste Materials Such As FA, GGBFS, And VPW Enhances Performance While Promoting Sustainable And Cost-effective Pavement Construction.
