AUTOMATIC EQUIPMENT FOR RAPID FREEZING AND THAWING OF CONCRETE IN WATER

THIS PAPER DESCRIBES THE CONSTRUCTION AND OPERATION OF AN AUTOMATIC, 25-SPECIMEN CAPACITY, FREEZING-AND-THAWING DEVICE FOR THE TESTING OF STANDARD CONCRETE SPECIMENS. THE CYCLE EMPLOYED IS RAPID FREEZING AND THAWING IN WATER IN ACCORDANCE WITH AASHO DESIGNATION T161 - ASTM DESIGNATION C290, WHICH IS THE METHOD SPECIFIED FOR THE EVALUATION OF BOTH AIR-ENTRAINING ADMIXTURES FOR CONCRETE AND AIR- ENTRAINING ADDITIONS FOR THE MANUFACTURE OF AIR-ENTRAINING PORTLAND CEMENT. DETAILS OF CONSTRUCTION, INSTRUCTIONS FOR OPERATION AND MAINTENANCE, AND A LIST OF COMPONENT PARTS WITH THEIR INDIVIDUAL COSTS AND OVER-ALL CONSTRUCTION COST, ARE PROVIDED IN THE APPENDICES. EXPERIENCES WITH OPERATION OF THE EQUIPMENT OVER A PERIOD OF FOUR YEARS AND TYPICAL TEST RESULTS OBTAINED ON CONCRETE SPECIMENS ARE DISCUSSED. /AUTHOR/
