The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste of grades of concrete by replacement of
5 ·Significance of Grading The aggregates are graded as per IS code 383 when the aggregate size is less than is called fine aggregate & more than is called coarse aggregate The aggregate gradation is determined by the fineness modulus method where aggregates are passing through the sieve as per IS standard to classify its size
