A SANDBLAST ABRASION TEST FOR SYNTHETIC AGGREGATE EVALUATION

THE NEED FOR AN AGGREGATE ABRASION TEST THAT WILL EFFECTIVELY DIFFERENTIATE BETWEEN THE QUALITY OF AGGREGATES OF VARIOUS UNIT WEIGHTS PROMPTED THE DEVELOPMENT OF A NEW TEST APPARATUS. THE METHOD SELECTED USED AIR-DRIVEN SAND AS THE ABRADING MECHANISM. RESEARCH FINDINGS BASED ON TESTS OF ONE NATURAL AND THIRTEEN SYNTHETIC AGGREGATES TENTATIVELY INDICATED THAT THE SANDBLAST TEST IS STATISTICALLY REPRODUCIBLE AND IS CHARACTERIZED BY IMPROVED DIFFERENTIATION BETWEEN VARIOUS AGGREGATES WHEN COMPARED TO RESULTS OBTANED WITH THE LOS ANGLES TEST. THE EVALUATION OF THE DIFFERENTIATING QUALITIES OF THE SANDBLASTING TEST IS BASED ON A CONSIDERATION OF THE PORE STRUCTURE, POROSITY, AND DEGREE OF THERMAL TRANSFORMATION OF THE SYNTHETICALLY PRODUCED AGGREGATES. /AUTHOR/
