RAPID SIEVE LINE DETERMINATION - DEVELOPMENT OF A METHOD FOR THE CONTINUOUS AND RAPID MEASUREMENT OF THE PARTICLE SIZE DISTRIBUTION OF SANDS AS A BASIS FOR IMPROVING AUTOMATIC CONCRETE MANUFACTURE

SCHNELLE SIEBLINIENBESTIMMUNG - ENTWICKLUNG EINER METHODE ZUR KONTINUIERLICHEN UND RASCHEN MESSUNG DER KORNVERTEILUNG VON SANDEN ALS GRUNDLAGE FUER EINE VERBESSERUNG DER AUTOMATISCHEN BETONHERSTELLUNG

A MEASURING PROCEDURE IS TO BE DEVELOPED BY MEANS OF WHICH THE SIEVE LINE OF A REPRESENTATIVE SAND SAMPLE OF ANY DESIRED FRACTION CAN BE DETERMINED. THE ACCURACY OF THIS ANALYSIS IS TO BE AT LEAST EQUAL TO THAT OF CONVENTIONAL SIEVE LINE ANALYSIS.
