SUITABILITY OF MANUFACTURED SAND FOR MAKING QUALITY CONCRETE

THE PAPER REPORTS THE LABORATORY INVESTIGATION OF SEVEN SAMPLES OF MANUFACTURED SAND (CRUSHER STONE DUST) OBTAINED FROM DIFFERENT STONE CRUSHERS AROUND DELHI, AND THE RESULTS ARE COMPARED WITH THOSE OF SAND OF MEDIUM FINENESS OBTAINED FROM ANOTHER LOCATION. THE PHYSICAL PROPERTIES OF CEMENT CONCRETE USING CRUSHER DUST AS FINE AGGREGATE IS ALSO REPORTED. THE LABORTORY INVESTIGATION INCLUDED PHYSICAL TESTS ON CRUSHER DUST AS FINE AGGREGATE, AND THE EFFECT OF CRUSHER DUST AS FINE AGGREGATE ON THE PHYSICAL PROPERTIES OF CEMENT CONCRETE. THE GRADATION AND FINENESS MODULUS OF FINE AGGREGATES ARE TABULATED. AN EQUATION USED TO CALCULATE SPECIFIC SURFACE IS PRESENTED. THE RESULTS OF MAXIMUM BULKAGE DETERMINATIONS ARE REPORTED IN A TABLE, AS ARE ALSO, THE RESULTS OF THE SODIUM SULFATE SOUNDNESS TESTS. THE TEST FOR MOTAR MAKING PROPERTY WAS PERFORMED AT 100 PERCENT FLOW AND 0.6 WATER/CEMENT RATIO ON CEMENT MOTARS USING DIFFERENT FINE AGGREGATES. THE COMPRESSIVE STRENGTH WAS DETERMINED IN 28 DAYS. THY COMPRESSIVE STRENGTH, FLEXURAL STRENGTH, ABRASION LOSS, DRYING SHRINKAGE AND BOND STRENGTH WITH STEEL WERE THE CEMENT CONCRETE PROPERTIES INVESTIGATED. THE RELATIVE COSTS OF THE DIFFERENT MIXES ARE REVIEWED. THE RESULTS OF THE INVESTIGATION ARE DISCUSSED AND CONCLUSIONS FORMED ON THE BASIS OF THESE RESULTS ARE LISTED.
