Abstract :

This Experimental Study Presents The Variation In The Strength Of Concrete When Replacing Sand By Quarry Dust From 0 To 100 In Steps Of 20. M30 And M40 Grades Of Concrete Were Taken For Study Keeping A Constant Slump Of 60mm. In Such A Situation The Quarry Dust Can Be An Economic Alternative To The River Sand. Quarry Dust Can Be Defined As Residue, Tailing Or Other Non-voluble Waste Material After The Extraction And Processing Of Rocks To Form Fine Particles Less Than 4.75mm. Usually, Dust Is Used In Large Scale In The Highways As A Surface Finishing Material And Also Used For Manufacturing Of Follow Blocks And Lightweight Concrete Draws Serious Attention Of Researchers And Investigators. From Test Results It Was Found That The Maximum Compressive Strength Is Obtained Only At 40 Replacement At Room Temperature And Net Strength After Loss Due To Hike In Temperature Was Above The Recommended Strength Value Due To 40 Replacement Itself. We Are Using The M30 And M40 Grade Concrete By Adding 20 And 40 Quarry Dust Used Was Designed By A Modified IS Method Were Casted And Compression, Split Tensile Strengths Conducted For The Age 3days Of 7 And 28 Days Were Obtained At Room Temperature. The Quarry Dust As A Partial Replacement Of Fine Aggregate With Super Plaster (VARA PLASTER SP 123) To Obtained High Workability And High Strength As A Chemical Mixture. This Result Gives A Clear That Quarry Dust Can Be Utilized In Concrete Mixtures As A Good Substitute For Natural River Sand Giving Higher Strength At 50 Replacement. Index Terms- Concrete, Quarry Dust, River Sand, Super Plaster, Compressive Strength Split Tensile Strength.
