Abstract
WE WILL DETERMINE THE FEASIBILITY OF IMPROVED METHODS FOR DETERMING AIR CONTENT IN FRESH CONCRETE. WE EXPECT THAT A STUDY OF VOLUME CHANGE WITH VARYING PRESSURE AND VACUUM WILL LEAD TO A METHOD THAT WILL INDICATE BOTH AIR CONTENT AND VOID SIZE, AND YIELD AIR CONTENTS THAT T ARE UNAFFECTED BY THE NONTHEORETICAL COMPRESSIBILITY OF SMALL VOIDS. WE WILL DETERMINE THE FEACIBILITY OF SIMPLER METHODS OF DETERMINING AIR CONTENT; THROUGH MEASUREMTN OF SAMLES ULTROSONIC PROPERTIES, THROUGH A COLOR INDICATOR, AND THROUGH DETRAINING AIR IN THE ROLL-A-METER BY VIBRATION AND VACUUM.
