USE OF CONCRETES CONTAINING ANTIFROST ADDITIVES DURING THE CONSTRUCTION OF BRIDGES /IN RUSSIAN/

THE EFFECT OF TEMPERATURE (DOWN TO -23 C) AND ANTIFROST ADDITIVES CALCIUM AND SODIUM CHLORIDE ON THE HARDENING PERIOD, STABILITY, AND STRENGTH OF CONCRETES USED IN THE CONSTRUCTION OF BRIDGES AND WATER PIPES IN THE NORTHERN REGIONS OF THE USSR IS DISCUSSED. THE FROST-RESISTANCE AND STRENGTH OF THE CONCRETES DEPENDS ON THE AMOUNT OF THE SALTS ADDED AND INCREASES WITH INCREASING SALT CONTENT UP TO 7.5% OF THE AMOUNT OF CEMENT USED, BUT THE USE OF THE SALT ADDITIVES IN AMOUNTS EXCEEDING 7.5% MAY HAVE A NEGATIVE EFFECT ON THE FROST-RESISTANCE OF THE CONCRETE AT LOW TEMPERATURES. TESTS REVEALED THAT THE STRENGTH OF CONCRETE BRIDGES AND PIPES CONSTRUCTED DURING THE PAST 10 YEARS VARIES BETWEEN 350 AND 500 KG (FORCE) /SQUARE CM. /CA/
