Experimental Study On Partially Replacing Concrete By Using Prosopis Juliflora Ash And Foundry Sand

Abstract

In Recent Years, The Main Importance Is On Green And Sustainable Development Throughout The World. Cement Industries Are Releasing The Numerous Gases, Which Is One Of The Main Reasons In Environmental Pollution. Also, Prosopis Juliflora Plant Now Becomes A Threat To The Environmental System. Since It Grows Up To 50 Ft Deep And Also It Absorbs More Ground Water. So, Using Prosopis Juliflora Ash (PJA) As Partial Replacement For Cement Is A Dual Purpose As Meeting The Demands Of Construction Industry And At The Same Time Providing A Sustainable Development. Generally, PJA Does Not Have Cementitious Property By Itself Which Is Responsible For Strength Generation. But In Presence Of Water It Reacts With Free Lime Obtained From Cement And Form Hydrated Products Such As C2S And C3S Which Helps In Attaining The Strength And Also Improving The Durability. Several Developing Countries Have Encountered Some Strain In The Supply Of Natural Sand In Order To Meet The Increasing Need Of The Infrastructural Development In Recent Year, To Overcome The Stress And Demand Of River Sand, Researchers And Practitioners In The Construction Industry Have Identified Some Alternative. One Of Them Is Foundry Sand, It Is A High Quality Silica Sand With Uniform Physical Characteristics And By Product Of Ferrous And Non-ferrous Metal Casting Industry. In This Project We Are Verifying The Above Thoughts, By Using PJA As Replacement To Cement At 25 To 40% With Every Increment Of 5%. Here, I Have To Find Out The Mechanical Properties (Compressive, Split Tensile) And Durability Properties (Acid Attack And Alkaline Attack) Of Concrete At Different Curing Periods And Were Compared With Control Mix Of M20 Grade
