AN ACCURATE LABORATORY TEST FOR DETERMINING THE ABSORPTION OF AGGREGATES

THE EXISTING METHODS FOR DETERMINING THE ABSORPTION OF AGGREGATES ARE DEPENDENT UPON INDIVIDUAL JUDGMENT. THEY ARE SUSCEPTIBLE TO HUMAN ERRORS AND THE RESULTS CAN VARY VERY CONSIDERABLY BETWEEN DIFFERENT TESTERS. FURTHERMORE, THEY GIVE DIFFERENT VALUES ACCORDING TO WHETHER THE FINE AGGREGATE IS TESTED AS A CONTINUOUSLY GRADED MATERIAL, OR WHETHER IT IS SIEVED INTO ITS VARIOUS SIZE FRACTIONS AND THE MEAN VALUE COMPUTED FROM TEST RESULTS FOR EACH FRACTION. VARIOUS TECHNIQUES WHICH MINIMIZED EXPERIMENTAL ERRORS AND WHICH WERE INDEPENDENT OF VISUAL OBSERVATIONS WERE THEREFORE INVESTIGATED. AN ACCURATE LABORATORY TEST HAS BEEN RECOMMENDED WHICH IS SUITABLE FOR BOTH RESEARCH WORK AND AS A REFERENCE DATUM FOR THE EXISTING METHODS.
