REPORT OF COMMITTEE ON METHODS OF HANDLING AND PLACING CONCRETE, A SYMPOSIUM ON VIBRATION OF PAVEMENT CONCRETE

FOUR REPORTS ON VIBRATION OF PAVEMENT CONCRETE WERE SPONSORED BY THE PROJECT COMMITTEE ON METHODS OF HANDLING AND PLACING CONCRETE. ONE COVERED FRENCH PRACTICE AND THE OTHERS PERTAINED TO THE RESULTS OF TESTS AND OBSERVATIONS IN WISCONSIN, KANSAS AND ILLINOIS. THERE HAD BEEN NO GENERAL ACCEPTANCE OF THE METHOD OF HIGH FREQUENCY VIBRATION TO IMPROVE THE QUALITY OF PAVEMENT CONCRETE. INCREASED STRENGTH WAS ABOUT 10 PERCENT FOR A GIVEN CEMENT CONTENT. DRIER, HARSHER MIXES COULD BE HANDLED RESULTING IN DENSER AND MORE DURABLE CONCRETE. IT WAS POSSIBLE TO USE LESS SAND AND WATER AND MORE COARSE AGGREGATE PER UNIT VOLUME OF CEMENT. FURTHER BENEFITS SHOULD RESULT WHEN THE OTHER UNITS ARE RE-DESIGNED TO HANDLE THE TYPE OF CONCRETE MOST SUITABLE FOR VIBRATION. THE APPLICATION OF VIBRATION USING EXISTING EQUIPMENT WAS TO BE SHOWN AS PRACTICAL AND ECONOMICAL.
