Experimental Investigation On The Strength And Durability Properties Of M30 Concrete By Partially Replacing Cement With Eggshell Powder

Abstract

This Study Investigates The Use Of Eggshell Powder (ESP) As A Partial Replacement For Cement In M30 Grade Concrete. With The Increasing Demand For Sustainable Construction Materials, ESP Offers An Eco-friendly Alternative Due To Its High Calcium Carbonate Content, Which Is Chemically Similar To Cement. The Primary Objective Of This Research Is To Evaluate The Impact Of Varying ESP Replacement Levels (5%, 7.5%, And 10%) On The Mechanical Properties And Durability Of M30 Concrete. The Study Assesses Compressive Strength, Water Absorption, Chloride Penetration, And Acid Resistance At Different Curing Periods (7, 14, And 28 Days). Results Show That ESP Enhances Both The Strength And Durability Of The Concrete, With 7.5% ESP Replacement Providing The Best Balance Of These Properties. The Findings Confirm That ESP Can Significantly Reduce The Environmental Impact Of Concrete Production By Replacing Cement, Which Is A Major Contributor To Carbon Emissions. This Study Provides A Deeper Understanding Of The Role Of ESP In Concrete, Offering Insights For Sustainable Construction Practices And Waste Material Utilization In The Industry.
