DETERMINATION OF THE CONSISTENCY OF CONCRETE BY THE COMPACTING RATIO METHOD
THE BULK DENSITY OF A LOOSELY CHARGED CONCRETE IS DEPENDENT ON ITS CONSISTENCY. THE RELATION OF THE VOLUME OF A LOOSELY CHARGED BATCH OF CONCRETE TO THE SOLID VOLUME OF THIS BATCH (FOR EXAMPLE AFTER COMPLETE COMPACTION) REPRESENTS AS 'COMPACTING RATIO' A SIMPLE MEASURE OF THE CONSISTENCY. FOR THIS PROCEDURE ONLY A PRISMATIC CONTAINER AND ANY TOOL FOR COMPACTION (VIBRATOR OR TAMPER) ARE NECESSARY. BY THIS METHOD THE CONSISTENCY OF CONCRETE WITH ANY MAXIMUM SIZE OF AGGREGATE CAN BE MEASURED IN THE RANGE FROM PULPY TO STIFF, AND THE COMPACTING RATIO EXTENDS FROM ABOUT 1.05 TO ABOUT 1.50. /AUTHOR/
