Strength Modifier of M30 and M40Concrete Partial Replacements with Rock Dust as Fine Aggregate
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 3
Abstract
The Quarry Rock Dust Can Be An Economic Alternative To The River Sand. Quarry Rock 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,Quarry Rock Dust Is Used In Large Scale In The High Ways As A Surface Finishing Material And Also Used For Manufacturing Of Hollow Blocks And Light Weight Concrete Prefabricated Elements.This Project Presents The Feasibility Of The Usage Of Quarry Rock Dust As Hundred Percent Substitutes For Natural Sand In Concrete. Design Mix For M30 And M40 Has Been Calculated Using Is 10262-2009 For Both Conventional Concrete And Quarry Dust Concrete. Tests Were Conducted On Cubes, Cylinders And Beams To Study The Strength Of Concrete By Using Quarry Rock Dust And The Results Were Compared With The Natural Sand Concrete.Cement Motor Ratios Of 1:3 And 1:6 Are Prepared And Observe The Percentage Of Water Absorption In Both Quarry Rock Dust And Natural Sand For Plastering.
