PROCEDURES FOR DETERMINING THE AIR CONTENT OF FRESHLY-MIXED CONCRETE BY ROLLING AND PRESSURE METHODS

APPARATUS AND METHODS ARE DESCRIBED FOR DETERMINING THE AIR CONTENT OF FRESH CONCRETE BY VOLUMETRIC AND PRESSURE METHODS. FIELD AND LABORATORY TESTS SHOW GOOD CORRELATION BETWEEN THE TWO METHODS. THE PAPER INCLUDES PROPOSED TENTATIVE METHODS BASED ON THE EXTENSIVE STUDIES WHICH WERE MADE TO DEVELOP THE PROPER APPARATUS, CALIBRATION AND TESTING TECHNIQUE FOR MAKING THE METHODS AS PRACTICAL AND DEPENDABLE AS POSSIBLE UNDER JOB CONDITIONS. /PCA/
