PHYSICAL PROPERTIES OF CONCRETE AT VERY LOW TEMPERATURES

PROBLEMS IN THE DESIGN OF UNDERGROUND PRESTRESSED CONCRETE TANKS FOR THE STORAGE OF LIQUEFIED NATURAL GAS INDICATED THE NEED FOR ADDITIONAL INFORMATION ON THE PROPERTIES OF CONCRETE AT EXTREMELY LOW TEMPERATURES. RESULTS OF AN INVESTIGATION OF COMPRESSIVE STRENGTHS, SPLITTING STRENGTHS, YOUNG'S MODULUS OF ELASTICITY, AND THERMAL CONTRACTIONS OF THREE SAND AND GRAVEL CONCRETES AND ONE LIGHTWEIGHT AGGREGATE CONCRETE AT VARIOUS TEMPERATURES FROM 75 TO -250 F ARE REPORTED IN THE PRESENT PAPER. YOUNG'S MODULUS OF ELASTICITY OF A PARTICULAR MOIST CONCRETE INCREASED FROM 5.5 SPI AT 75 F TO 8.5 X 1000000 PSI AT 250 F. THE COMPRESSIVE STRENGTH OF THIS CONCRETE INCREASED FROM ABOUT 5000 PSI AT 75 F TO OVER 17,000 PSI AT -150 F. /PCA/
