THE ANALYSIS OF FRESH CONCRETE-AN EXAMINATION OF ITS ACCURACY AS A FIELD TEST
DATA OBTAINED ON TWO EXPERIMENTAL ROADS ARE USED TO EXAMINE THE ERRORS ARISING WHEN THE BRITISH STANDARD METHOD OF ANALYSING FRESH CONCRETE IS USED ON CONSTRUCTION SITES TO ASSESS THE UNIFORMITY OF CONCRETE. IT IS CONSIDERED THAT IMPROVED METHODS OF SAMPLING ARE NEEDED TO OBTAIN RESULTS REPRESENTATIVE OF COMPLETE BATCHES, AND THAT UNTIL ALTERNATIVE TECHNIQUES HAVE BEEN EVOLVED REPEATED CALIBRATION TESTS ARE NECESSARY TO DETERMINE THE VARIATION IN THE CONSTANTS RELATING TO THE SPECIFIC GRAVITY OF THE AGGREGATE AND THE PROPORTION OF VERY FINE MATERIAL PRESENT. /RRL/
