Partial Replacement Of Cement With Marble Powder In M20 Grade Of Concrete

Abstract

Concrete Is One Of The Most Widely Used Construction Materials Because Of Its Strength, Durability, And Versatility. However, Large-scale Cement Production Creates Serious Environmental Problems Due To Excessive Carbon Dioxide Emissions And Depletion Of Natural Resources. At The Same Time, Marble Industries Generate Huge Quantities Of Waste Marble Powder During Cutting, Polishing, And Finishing Operations. Improper Disposal Of This Waste Causes Air Pollution, Soil Contamination, And Environmental Degradation. The Present Study Focuses On The Utilization Of Marble Powder As A Partial Replacement Of Cement In Concrete Production To Achieve Sustainable And Eco-friendly Construction Practices. In This Investigation, Marble Powder Was Used As A Partial Replacement Of Cement In Different Proportions For M20 Grade Concrete. Various Tests Were Conducted To Evaluate The Mechanical Properties Of Concrete, Including Compressive Strength, Split Tensile Strength, And Flexural Strength. The Study Observed That The Addition Of Marble Powder Improved The Strength Characteristics Of Concrete Up To An Optimum Replacement Level Due To The Filler Effect And Improved Particle Packing Within The Concrete Matrix. Beyond The Optimum Percentage, The Strength Gradually Decreased Because Of Reduction In Cementitious Bonding Properties.
